Question

1.Bag of marbles: 5 red, 7 white, 11 blue (23 total). Reachin bag and select 5.

a.What is n(S)?

b.What is probability that all 5 selected are red?

c.What is probability that all 5 selected are white?

d.What is probability that all 5 selected are blue?

e.What is probability that at least 1 is blue?(Hint: easier to solve using?(???????1????)=1−?(0????))

f.What is the probability that you select exactly 2 red, 2 white, and 1 blue?Use this stragegy:n(E) = (number of ways to choose 2 of 5 red)*(number of ways to choose 2 of 7 white)*(number of ways to choose 1 of 11 blue)n(S) = answer from part adivide n(E)/n(S)
