Suppose q and r are independent events, and p(q)= 0.39, p(r)= 0.85. find p(q and r)

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 :)
