If you flip three fair coins, what is the probability that the first two flips will both be heads, and the third flip will be either heads or tails?

Answer 1

1st flip probability (50% or 0.5)

2nd flip probability (50% or 0.5)

third flip probability (100% or 1.0)

Since these are independent of eachother. Simply mutiply each flip out.

0.5*0.5*1.0 = 0.25 or 25%
