Math has literally never been a struggle to me but probability pisses me off

Thank you so much for this video! I understand the basic probabilities, but as soon are we get to these word problems I was so confused. I am so glad I found this video to help me understand where I was going wrong.

Try making an audio recording, that way when you read your notes you can listen. I used that strategy in graduate school and it helped a lot. Good luck with your sat test.

In the last problem, how did you get 5 over 3 = 10??? I heard you say, "5 common 3 is 10." What does that mean?? Thanks, great job teaching all of the other problems.

I'm very late, but I'll just post this for others who are asking the same question. 5C3 or 5 choose 3 refers to how many combinations are possible from 5 items, taken 3 at a time. Find 5C3 from Al, Betty, Charlie, Delilah, Erin. The number of possible ways you could take 3 people from that list (Al, Betty, Charlie, Delilah, Erin) are: Al / Betty / Charlie, Al / Betty / Delilah, Al / Betty / Erin, Al / Charlie / Delilah, Al / Charlie / Erin, Al / Delilah / Erin, Betty / Charlie / Delilah, Betty / Charlie / Erin, Betty / Delilah / Erin, Charlie / Delilah / Erin. So 5 choose 3 = 10 possible combinations.

Please I don’t get you

I hate statistics so much. DImes and Nickles U.S & Canada: P(AorB)=p(A)+p(B) - p(A and B) to me that formula means you always get zero. How can you add A&B and then subtract A&B and get anything but zero? Don't tell me that's not what it means because that's how it is written. It should be Minus - P(A). or -P(B). My brain just can't take it. :( Looks like I'm dropping this course until next year.

Just slow down and write the problem down. Then just use the formula step by step and you'll be fine.

That's because + and * are different. Simplify things by just everything is 0.25. 0.25 + 0.25 = 0.5. 0.25 * 0.25 = 0.0625. Even if we're talking about probability. 1 + 2 (A + B) = 3, 1 * 2 (A * B) is 2, they are not the same.

Perhaps I didn't understand the last problem correctly. If I use binomial coefficients: (1/4)^3 * (3/4)^2. I get 8.78x10^-3, which is slightly off from the answer. I'm not sure what I'm doing wrong.
