Q:
I am rolling 4 dice total. I am trying to find the probability of having three out of the four dice rolled be equal to or greater than 4 (i.e. % of 3 of the 4 dice rolling a 4,5,or 6).
--------------------------------------------------------------------------
A:
The probability that a die rolled a 4,5, or 6 is 1/2 or 0.5.
Let X = number of dice out of the four dice rolling a 4,5, or 6.
X follows a Binomial Distribution with n = 4 and p = 1/2.
P(X = 3) = =
