Suppose the dial on the spinner is spun 2 times in a row. X is the number of times the dial lands on region B.
Which table represents the probability distribution for the variable X?
Prob that the spinner lands on B 0 times = 3/4 * 3/4 = 9/16
Prob that the spinner lands on 1 time = (1/4) (3/4) + (3/4)1/4) = 6/16 = 3/8
Prob that the spinner lands on B 2 times = (1/4) (1/4) = 1/16
