Question 549537: Binomial probability: a card is randomly selected from the deck and its shape and number are recorded. suppose this is repeated 10 times. what is the probability that exactly:
a. four out of then are squares.
in the figure it shows 5 triangles numbered 1 2 2 3 3
4 circles numbered 1 1 2 3
6 squares numbered 1 2 2 2 3 3
i know the formula
nCkpKp(N-K)
10C4p4p10-4
i don't know how to get the p Answer by stanbon(75887) (Show Source):

Binomial Problem with n = 10 and p(square) = 6/15
-----
P(x = 4) = 10C4*(6/15)^4*(9/15)^6 = = binompdf(10,6/15,4) = 0.2508
