Probability(P) (X = 2) = 0.36
:
P(X = 3) = 0.12
:
P(X = 4) = 0.32
:
success is defined as 2, 3, 4
:
*****************************************************
P is 1/4 + 1/4 + 1/4 = 3/4 = 0.75
:
Note that experimental P is 0.36 + 0.12 + 0.32 = 0.80
:
If you were to spin the spinner another 100 times you
would get different results but the results would be
close to 0.75
