Answer:
P (q and r) = 0.3315
Explanation:
We are given that:
P (q) = 0.39
P (r) = 0.85
Since the two events are independent, therefore, the formula that we will use to get P (q and r) is as follows:
P (q and r) = P (q) * P (r)
Based on the givens:
P (q and r) = 0.39 * 0.85 = 0.3315
Hope this helps :)
