FindP(R).

Short Answer

Expert verified

The required probability is P(R)=0.15.

Step by step solution

01

Given Information

A jar of 150 jelly beans contains 22 red jelly beans, 38 yellow, 20 green, 28 purple, 26 blue and the rest are orange.

02

Explanation

Number of orange jelly beans,

=150-(22+38+20+28+26)

=150-134

=16

Let B=the event of getting a blue jelly bean

Let G=the event of getting a green jelly bean.

Let O=the event of getting an orange jelly bean.

Let P=the event of getting a purple jelly bean.

Let R=the event of getting a red jelly bean.

Let Y=the event of getting a yellow jelly bean.

The favorable number of cases is 22and the total cases are150to calculate the probability of getting a red jelly bean. The probability of getting a red jelly bean is as follows:

P(R)=22150

=1175

=0.15
