The probability that Joe will be accepted at one, and only one, university is 0.45 or 45%.
Step-by-step explanation:
We are given that Joe is considering pursuing an MBA degree. He has applied to two different universities.
The acceptance rate for applicants with similar qualifications is 25 percent for University A and 40 percent for University B.
Let the probability that Joe will be accepted for University A = P(A) = 0.25
Probability that Joe will be accepted for University B = P(B) = 0.40
Now, Probability that Joe will be accepted at one, and only one, university is given by ;
Accepted for University A but not for University B + Accepted for University B but not for University A
= [P(A) (1 - P(B))] + [P(B) (1 - P(A))]
= (0.25 0.60) + (0.40 0.75)
= 0.15 + 0.30 = 0.45
Hence, the probability that Joe will be accepted at one, and only one, university is 0.45.
