Answer:
D
Step-by-step explanation:
ince the only colors are white, green, yellow, red, and purple, we can see that NOT getting red or purple is the same as GETTING white, green or yellow
So, P(NOT getting red or purple) = P(GETTING white, green or yellow)
There are 60 jellybeans in total.
Number of jellybeans that are white, green or yellow = 22 + 18 + 11 = 51
So, P(GETTING white, green or yellow) = 51/60
= 17/20
= 0.85
