Question

If six pennies are tossed onto the table, what is the probability of seeing two heads and four tails?

Answer 1

how many ways can you arrange them?

Answer 2

\[\binom{n}{r}p^rq^{n-r}\]

Answer 3

if p=q this amounts to:\[\binom{n}{r}p^n\]

Answer 4

they're being tossed all at the same time, not one by one

Answer 5

doesnt really matter

Answer 6

one by one we can get:

t h h t t t

or if we throw them all at once

t h h t t t

Answer 7

ok thx i see, so it's 0.234375?

Answer 9

15 * 1/2^6 whatever that turns out to be eh

Answer 10

well as a fraction it'd be 15/64

Answer 11

yeah, thatll be it

Answer 12
