Problem Solving

Of 30 applicants for a job, 14 had at least 4 years of experience, 18 had degrees, and 3 had less than 4 years of experience and did not have a degree. How many of the applicants had at least 4 years of experience and a degree?

A. 14
B. 13
C. 9
D. 7
E. 5

The OA is E.

I'm really confused with this PS question. Experts, any suggestion?

I know that 30 - 3 = 27 had at least 4 years of experience and/or a degree. How can I determine the exactly number of applicants that has at least 4 years of experience and a degree?

Thanks in advance.
