The probability that a fan is waving a banner given that the fan is cheering for team A is 0.25.

Step-by-step explanation:

The percentage of fans cheering for team A is, 80%.

The percentage of fans waving banners and cheering from team A is, 20%.

The probability that a fan is cheering is: P (C) = 0.80.

The probability that a fan is waving banners and cheering is:

P (W ∩ C) = 0.20.

The conditional probability of an event X provided that another event A has already occurred is:

Compute the conditional probability that a fan is waving a banner given that the fan is cheering for team A as follows:

Thus, the probability that a fan is waving a banner given that the fan is cheering for team A is 0.25.
