I don't like all these pop culture references. Like all the songs at the end of another episode or Cole Sprouse (I have no idea who that is, or even IHOP - here in Europe there is no IHOP (at least I haven't seen any, so when this happens I'm sitting like -Oookay, whatever. - (And yes, I know I don't have to be familiar with all these things in order to understand the video. I'm just saying that it slightly annoys me)

I think that when calculating the probability of P(A or B, we shouldn't calculate the probability of P(A and B) at all. So I think the formula should be like this: P(A or B) = P(A) + P(B) - 2P(A and B. That way, we can calculate the probability of only A or B occurring. The video says P(A or B) = P(A) + P(B) - P(A and B. Maybe our definition of the word 'or' is different? Please correct me if I'm wrong.

I appreciate people who take the time to put learning videos online, especially math videos. But I must say the pace of this video is too fast. I saw too many imponderables during the first minute of the video where I had to pause and go back as well as the rest of the video. I understood everything after stopping and rewinding but slow down a bit.

At 3: 52, I think what Adriene meant should be -Since P(tails and 6) is not equal to zero, these two events are not mutually exclusive- instead of -Since P(tails or 6) is not equal to zero. -

Please don-t use examples of people who some of older folks don-t know or care about. Using Cole whatever was distracting and not helpful. Otherwise your information is so helpful.

I think that at 4: 13 the title and the formula are not matching, the title says the prob of tails AND 6, but the formula says p(tails OR 6. I am confused.

The Venn diagram that has No Cole overlapping 'Cole' and also completely overlapping 'ice cream' is a bit confusing. Am I missing something?

can you guys slow down when teaching at crash course? you are really helpful, but you are bombarding me with words at a tremendous speed!

I didn't understand anything in class because my teacher talks so fast but I finally get it, even though I'd already failed his test XD

Finally. The first 13 videos was pretty simple. Now I feel like actually learning somethign that i wasnt taught in 3rd-5th grade.
