Answer:
b) 0.45
Explanation:
The probability that Joe will not be accepted in either university is the product of the probability that he would not be accepted at University A by the probability that he would not be accepted at University B. (The probability of not being accepted is 1 minus the probability of being accepted):
![P(neither) = (1-P(A))*(1-P(B))\\P(neither) =(1-0.25)*(1-0.4)\\P(neither) =0.45](https://img.qammunity.org/2021/formulas/mathematics/college/kn3kzaj5hc7mhhu3nrjzubp6s6ea75q2y4.png)
The probability that Joe will not be accepted at either university is 0.45.
