C. Brandon. He has a 0.63 probability of attending both activities.
Step-by-step explanation:
Probability of attending Probability of attending
the Saturday activity the Sunday activity
Aisha 0.90 0.68
Brandon 0.71 0.89
Given that attendance at one activity is independent of attendance at the other, the probability that Aisha attends both activities is: 0.9*0.68 = 0.61, and the probability that Brandon attends both activities is: 0.71*0.89 = 0.63
