Answer:
33% probability that the company will win at least one of the two contracts
Explanation:
We solve this problem building the Venn's diagram of these probabilities.
I am going to say that:
A is the probability that a company is awarded the first contract.
B is the probability that a company is awarded the second contract.
We have that:

In which a is the probability that a company is awarded the first contract but not the second and
is the probability that a company is awarded both contract.
By the same logic, we have that:

The probability that it will get both contracts is .13.
This means that

The probability that it will be awarded a second contract is .21
This means that




The probability that a company will be awarded a certain contract is .25
This means that




What is the probability that the company will win at least one of the two contracts?

33% probability that the company will win at least one of the two contracts
