At a basketball game,80 of the fans cheered fpr team A in the same crowd,20 of the fans were waving banners and cheering for team A. What os the probability that a fan waved a banner give that the fan cheered for team A

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.

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)
