Question 1132436


the eight outcomes are, and to answer the question properly, X goes in place of "F:
MMM--0.18 from 0.5*0.6*0.6
MMF--0.12 from 0.5*0.6*0.4
MFM--0.08 from 0.5*0.4*0.4
MFF--0.12 from 0.5*0.4*0.6
FFF--0.18
FFM--0.12
FMM--0.12
FMF--0.08

They add to 1.00
for 2M 1F the probability is 0.32
for at least one F is 0.82
