I hope this helped!
Let X be the number of cars recovered from stolen cars. Let n be the total number of stolen cars and p be the probability that car will be recovered.
Given: n=10, x=5
It is given that a car with a certain protection system will be recovered 87% of the time. It means probability of recovering a car is p=0.87
Probability that 5 out of 10 stolen cars will be recovered is
P(X=x ) = 
P(X=5) = 
P(X=5) = 0.0047
The probability that exactly 5 out of 10 stolen cars will be recovered is 0.0047
