Question

1. An urn contains one red ball (R), one white ball (W), one blue ball (B), one pink ball (P), and one green ball (G). An experiment consists of selecting two balls from the urn WITH replacement.

a. List the sample space for this experiment. One sample space possibility is RR.

b. List the event a blue ball or green ball is picked.

c. What is the probability that a blue ball OR green ball is picked?

Answer 1

Given: An urn contains one red ball (R), one white ball (W), one blue ball (B), one pink ball (P), and one green ball (G). An experiment consists of selecting two balls from the urn with replacement.

To find: a. List the sample space for this experiment. One sample space possibility is RR.

b. List the event a blue ball or green ball is picked.

c. What is the probability that a blue ball OR green ball is picked?

Solution:

A. One sample space possibility is RR= 1C1/5C1 into 1C1/5C1

=1/25

B. List the event a blue ball or green ball is picked=

Event for blue= 1C1= 1

Event for green= 1c1= 1

C. probability that a blue ball OR green ball is picked= 1C1/5C1 into 1C1/5C1

=1/25

a. 1/25

b. 1

c. 1/25
