Two coins are tossed. What is the conditional probability that two heads result given that there is a t least one head?
let S be the sample space
S = {{HH},{HT},{TH,{TT}}
P(HH|HT,TH,HH) = P(HH n HT,TH,HH)/P(HT,TH,HH) = (1/4 * 3/4) / (3/4) = 1/4
is this correct? I'm finding it hard to determine what the question is actually asking
