A ball is drawn randomly from a jar that contains 9 red balls, 2 white balls, and 3 yellow balls. Find the probability of the given event. Write your answers as reduced fractions or whole numbers.

Question

(a) P(A red ball is drawn) =   

(b) P(A white ball is drawn) =   

(c) P(A yellow ball is drawn) =   

(d) P(A green ball is drawn) =   

Answer 1

P(a red ball is drawn) = (# of red balls)/(total # of balls in jar)

= 9/14

P(a white ball is drawn) = (# of white balls)/(total # of balls in jar)

= 2/14 or 1/7

P(a yellow ball is drawn) = (# of yellow balls)/(total # of balls in jar)

= 3/14

P(a green ball is drawn) = (# of green balls)/(total # of balls in jar)

= 0/14 or 0
