Thank you for this sir. Sad to see us spending so much to be taught this over 2 hours, when people like you have videos for free at 10x the efficiency.

[@crowsmathclass]

Thank you. Glad it helped.

[@tristansalvador6127]

This makes much more sense now. Thanks!!

[@crowsmathclass]

You’re welcome.

Sir I am currently struggling with my mechanics of rigid bodies in my engineering subject and I have upcoming exam for statistics. This video came in clutch I understood it way much better than my stupid Bernoulli wannabe professor

[@crowsmathclass]

Glad it helped. Good luck on your exam.

heyy thanks for it! it was helpful~
There is sth that i wonder, can we find the right answers with cross solutions?
For example, suppose there are 20 people, 8 of whom are girls, in a group. Let's form a team of 5 people and ask to have 3 girls. I'm trying to do cross solutions. When the answer to this question is solved with binomial, 0.2304 is found. I also want to solve it with geometric distribution. Statistics is a very rich content, is it not possible for us to do this? i couldn't solve it with geometric one, if i can i'll try to find the solutions with bernoulli and then possion etc

[@wendyforehead2141]

sir what if the probability is in range for example 3

[@crowsmathclass]

You would just the probabilities for 4 and 5.

How does one punch it in the calculator .

[@Praticia62]

but I cannot look at the table in my midterm.

[@crowsmathclass]

You’re teacher must be making you use the formula.

[@sallywinston5305]

I wish you had used the formula for example 2 question 1 because you lost me there :(

[@crowsmathclass]

It would be just like problem 1 except you would have to apply the formula to each of the five. r=0, r=1, r=2, r=3, r=4.

[@sallywinston5305]

​@@crowsmathclass Each of the five? I am talking about the six question multiple choice quiz and the probability of answer exactly half of the questions correctly.

[@crowsmathclass]

You could use the formula.
n=6
r=3
p=.2
q=1-.2=.8

[@sallywinston5305]

@@crowsmathclass I did that and I got 0.08192, not 0.9830

[@crowsmathclass]

You know looking at that table it may have the wrong values in it. I did a google search for the table and just downloaded that table. If you have a table look it up on that table and compare to the one I used. Thanks for letting me know. I didn’t think to check the values in the table I got off the internet. You may be correct. Sorry about the confusion.
