I have watched many videos and didn’t understand, your video gave me all that I need !thank you

[@philipscomputerrepair]

You are the best on this Normal distribution probability you really saved us. we need more videos of statistics. may God bless you. from Namibia.

[@OninabResources]

Thanks. I will try my best. Amen to your prayer.

[@user-my3bh4wk2u]

This video saved my semester final.Take ❤ from 🇧🇩.

[@RameshTT.]

This video provide step by step explanation and i can understand normal distribution problem. Thank you.

[@OninabResources]

You are welcome. We are glad to read your feedback.

[@Jenifer-uo3df]

Thank you so this rilly helped me alot like I have an exam nxt wk and I knew nothing on this topic buh after watching this I now able to solve problems

[@OninabResources]

You are welcome.
We are glad it helped.
Best of luck!

thank you !!

[@ridonngandu8290]

God bless you buddy

[@michelmarshall890]

I will watch the video again just to cement the concept thanks much

[@OninabResources]

Nice one

[@brianatanda9253]

Well explained. Thank you.

[@OninabResources]

You're welcome!
We are glad you enjoyed one of our videos.

[@CBKCUSTOM]

can you help me understand where or why 0.5 is used in the equation thankyou

[@OfentseModirwa]

Your video is helpful🤝

[@OninabResources]

We appreciate your feedback.

[@Maria_farah]

thank you its clear to understand.

[@OninabResources]

You are welcome.

[@michelmarshall890]

Thanks you sir you explained very clearly

[@OninabResources]

You are welcome.

[@AndiswaSokhela-br7cc]

the part that i dont understand is when we're adding those 0.02 etc to the z score why are we adding that and how do you know which number to add?

[@raghar3546]

Thanks❤

[@dawitbelay141]

Whats the 0.5 all idea, can't we subtract from one 1,as it is al 1 probability?

[@user-uv4kd6kv9k]

Why minus 0.5 in d first example

[@patienceainembabazi1254]

The total area to the left side is 0.5 to get it's probability u subtract the probability given to get the area (probability) of the remaining shaded part 👍

[@Mma_JC]

Since the total area under the curve is 1. It simply implies that the area on both sides of the mean is 0.5 each.
Now recall that the Z table gives the area between 0 and the Z value. Hence 0.5 - 0.1255 gives the wanted area.

[@perpetualchisom3065]

The aim is to get the area of the shaded region, and the value of each side by the broken line is 0.5.
Now, you must get the unshaded to know the shaded which is the value gotten from the table.
Then you subtract these value from 0.5 to get the shaded part.

[@katohussein1666]

It's amazing your a genius man

[@ThePaediatrics]

Please explain why we subtract 0.3413-0.0636

[@salmanbaloch1868]

Sir book name

[@MarqosababaDinaga-ny6iz]

thank very much

[@OninabResources]

You are welcome

[@thomasshuhulichimbeja7441]

be blessed

[@abrahamlawson3198]

What z table did you use?
Are there different z tables?

[@OninabResources]

Yes there are. Use the one recommended by your school please.

[@fridaekandjo]

wait wasnt it suppose to be o.5+ in the first first example?? or why is it minus if its less than?

[@cabdikariimsiciid1752]

In the last question D why you aren't add the two area and after subtract 0.5

[@ThePaediatrics]

someone please explain this

[@carolynesein345]

I also thought of the same idea. someone kindly explain this

[@AminuDaliyu]

Even me too, I thought should be 0.5-p1-p2

[@moatlhodibagayi-vk5gt]

Check the z score ranges...and what area they cover and u will notice why he substracted ...just use diagrams to notice the area covered from zero of the z axis

[@dawitbelay141]

At 10 : 50 not clear

[@kgosieking5525]

O.5????

[@carolynesein345]

because total area under the curve is 1. so a half of it will be 0.5. that was explained before solving the question.

[@alfahaddawami3494]

where does o.5 came from

[@kelvintendaikwande9601]

P(z=0)=0.5 from the table

[@moatlhodibagayi-vk5gt]

Im if i get ur question..normally the normal curve has a total probability area of 1 and is symmetrical about center...so the other left part of mean center is 0.5 percent area and the right of mean is also 0.5 which all attributes to 1

[@shuqranfazirat1269]

but why have changed the sign on second example

[@frankkyando5539]

The idea is to get the area between the two value of Z. To do that we ind the area from 0 to -1 and minus it with the area from 0 to -0.16

[@patienceainembabazi1254]

Because it is symmetric ....we don't take negatives ..that's why we change the sign also but when using a calculator ..the sign remains

[@NoahMusungu-gm9ds]

I have really apriciated the service

[@NoahMusungu-gm9ds]

I have really apriciated the service

[@kumaripriyanka9743]

How you got 0.5 value

[@francklyneochieng5771]

Each half of the curve represents 0.5 of the total area which is one

[@BirhanuAnley]

Thanks
