Final answer:
The probabilities p1 and p2 can be found using the formulas p1 = x1/n1 and p2 = x2/N₂.
Step-by-step explanation:
To find the probabilities p1 and p2, we use the formulas p1 = x1/n1 and p2 = x2/N₂.
The probability p1 represents the proportion of engineering students at Arizona State University who own Apple computers, and it is calculated by dividing the number of engineering students at ASU who own Apple computers (x1) by the total number of engineering students at ASU (n1).
Similarly, the probability p2 represents the proportion of engineering students at Virginia Tech who own Apple computers, and it is calculated by dividing the number of engineering students at Virginia Tech who own Apple computers (x2) by the total number of engineering students at Virginia Tech (N₂).
