Probability of getting a cracked egg at the store is 7%:

a) What is the probability that a caron of 12 eggs will contain at LEAST one cracked egg? (hint: use indirect method to answer).

b) Determine the number of cracked eggs you expect to find in a gross of eggs? (A 'gross' is 12 dozen OR 144).

I am totally LOST . Would I be using Binomial Distribution with this formula: p(x)=C(n,x)·p^x·q^n-x
