Ask yourself:
What is the probability that NONE of the mothers
will choose peanut butter? Call this
probability P(0)
------------------
The probability that AT LEAST ONE mother chooses
peanut butter is whatever probability is left over, or
----------------
I say that
= ( not PB ) x ( not PB ) x ( not PB ) . . . for all 12 mothers
So, the probability is:
.999998118
Definitely get another opinion on this
but I think I'm right
