Use the list and calculation method to answer the following questions. Show your work at each step.

4. You draw three cards (with replacement) from a standard deck of cards. What is the probability that

a. exactly one will be red: .125 + .125 + .125 = .375

b. none will be red, and: .125

c. more than two will be red: .125

Outcome Probability No. of Hits

RRR (.5)(.5)(.5) = .125 3

RRB (.5)(.5)(.5) = .125 2

RBR (.5)(.5)(.5) = .125 2

RBB (.5)(.5)(.5) = .125 1

BRR (.5)(.5)(.5) = .125 2

BRB (.5)(.5)(.5) = .125 1

BBR (.5)(.5)(.5) = .125 1

BBB (.5)(.5)(.5) = .125 0
