Question

Find the probability of getting 2 tails when 3 fair coins are tossed

Answer 1

all events = 2^3 = 8

Answer 2

the events 2 tails = 3!/2!1! = 3

Answer 3

So it has to be: TTH, or THT, or HTT.
The probabilities of H and T are both 1/2 (fair coins)
Next step?

Answer 4

so, the probility = ....

Answer 5

*probability

Answer 6

Proability of TTH is (1/2) * (1/2) * (1/2) =
Same for the other outcomes, so ...

Answer 7

Hey RadEn, I like the different methods we use to solve this ;)
