You can put this solution on YOUR website! Suppose events A and B are independent and P(A)=0.6, P(B)=0.2. Find the probability that at least one of A and B occurs.
Step 1. Since the events are independent, we can multiply, their probabilities.
Step 2. Therefore, P(A and B)=P(A)P(B) for independent events. As a result, the probability of A and B is (0.6)*(0.2)=0.12.
I hope the above steps were helpful.
