A certain jar contains 100 jelly beans: 50 white, 30 green, 10 yellow, 5 red, 4 purple, and 1 black. If a jelly bean is to be chosen at random, what is the probability that the jelly bean will be neither purple nor red?
A
0.09
B
0.11
C
0.55
D
0.91
Correct Option - D
Explaination
P(purple)
= 4/100
P(red)
= 5/100
P(neither purple nor red)
= 1-(4/100)-(5/100)
= 1-(9/100)
= 91/100
= 0.91
