Answer:

0.95

Step-by-step explanation:

To answer this question, we need to find the probability of selecting a female attendee and a college professor. Then we calculate the needed probability.

Firstly, we calculate the probability of selecting a female attendee. There are 2,575 females. Hence, the probability of selecting a female attendee is 2575/4950

Now, we move on to calculate the probability of selecting a college professor. The probability here is 2110/4950

The probability of selecting either of the two is simply the addition of both probabilities:

P = 2575/4950 + 2110/4950 = 0.95
