Answer:
P = 25/42
Step-by-step explanation:
We are asked to calculate the probability that if two items are selected from two different boxes, what is the probability that bought are non-defective.
In the first box A, the probability of selecting a non-defective item is 5/7
In the second box B, the probability of selecting a non-defective item is 5/6
Now the probability of selecting 2 items, one from each of the boxes and both are non-defective are as follows;
5/6 * 5/7 = 25/42
A. 3x-7y and -7+3x that is the correct answer
