B Correct answer
Explanation

Probability = P(Meeting) * P(Alex attends | Meeting) = 0.60 * 0.70 = 0.42.

AI explanation

We use the multiplication theorem of probability to find the joint probability of two independent events. The probability that a meeting takes place is 0.60, and the probability that Alex attends a meeting that takes place is 0.70. Multiplying these two probabilities together yields 0.60 times 0.70, which results in a final probability of 0.42.
