Answer: 0.21

Step-by-step explanation:

Let A denotes the event that employees are college graduates.

B denotes that the event that employees have more than ten years of experience.

As per given , we have

P(A)=0.51

P(B)=0.47

P(A∪B)=0.77

We know that , [tex]P(A\cup B)=P(A)+P(B)-P(A\cap B)[/tex]

[tex]0.77=0.51+0.47-P(A\cap B)[/tex]

[tex]P(A\cap B)=0.51+0.47-0.77=0.21[/tex]

Hence, the probability that a randomly selected employee will have more than ten years of experience and be a college graduate = 0.21
