One head, one tail 95

Answer 2

answer mine, I'll answer yours

Answer 3

Can you answer this? What was the joke from 17:51 - 18:03 in this vid and why did she spray the air freshener https://www.youtube.com/watch?v=Rhn5uobZAyQ?

Answer 4

what?

Answer 5

@Cal.lavender Help?

Answer 6

The sample space has size 23=823=8 and consists of triples
HHHHTTTTHHTTHHTTHTHTHTHT
HHHHHTHTHHTTTHHTHTTTHTTT
The events
{0 heads}{1 head}={TTT},={HTT,THT,TTH},
{0 heads}={TTT},{1 head}={HTT,THT,TTH},
and I'll let you figure out the other two.

The probabilities are, for example,
P({1 head})=38.
P({1 head})=38.
This is called a binomial distribution, and the sizes of the events "got kk heads out of nn coin flips" are called binomial coefficients.

Answer 7

This is very confusing

Answer 8

Is there a way u can make it more simple?

Answer 9

The outcomes you are looking for are either THH, HTH or HHT. Taking a look at for example THH: the possibility to toss T or H is 0.50.5. Thus the possibility to throw T and then H and then H is 12⋅12⋅12=1812⋅12⋅12=18. But since we have three ways to "achieve" the desired result, the possibility of throwing exactly tow heads in three tosses is 18+18+18=3818+18+18=38.

If you continue you like this, you'll find that the possibilites of all possible outcomes (THH, TTH, TTT, HTT ...) add up to 1 indeed.
