known that 10% will have defect; random sample of n = 100

Based on past history, a car manufacturer knows that 10% (p=0.10) of all newly made cars have an initial defect. In a random sample of n = 100 recently made cars, 13% (p-hat = 0.13) have defects.

What is the probability of getting p-hat > .13 if p = .10?

p-hat ..how??
