Answer 1

I think your Numlock key acted up

Answer 2

A container contains 2 red, 3 white, and 5 yellow balls. Suppose that once a ball is drawn it is not replaced. What is the probability that 2 red balls will be drawn in 2 tries? (Express your answer as a fraction.)

Answer 3

2 red out of 10 possibilities, then 1 out of 9. Mathematically, that's 2/10*1/9 = 1/45

Answer 4

(2/10)X(1/9) = 1/45
