Final answer:
To find the probability that both universities will make her an offer, multiply the individual probabilities of each university making an offer, assuming the events are independent.
Step-by-step explanation:
The question asks for the probability of two independent events happening simultaneously. Specifically, it asks what is the probability that both universities will make her an offer. This requires knowing the individual probabilities for each university to make an offer and assuming independence, multiplying these probabilities together to obtain the joint probability.
For example, if one university has a probability of 0.75 (or 75%) of making an offer and the other university also has a probability of 0.75 of making an offer, then the combined probability is computed as 0.75 * 0.75, which equals 0.5625 or 56.25%.
This method of calculation is derived from the multiplication rule for independent events, P(A and B) = P(A) * P(B), where A and B are independent events.
