Chapter P, Section 1, Exercise 042
Pancakes
A friend makes three pancakes for breakfast. One of the pancakes is
burned on both sides, one is burned on only one side, and the other
is not burned on either side. You are served one of the pancakes at
random, and the side facing you is burned. What is the probability
that the other side is burned? (Hint: Use conditional
probability.)
Enter the exact answer.
P(other side is burned): _____________________ 0.5 and...
