Problem 111Multiple Choice

A day of the week is selected at random. Determine the sample space, the outcomes in the event that the day starts with the letter “S,” and the number of outcomes in this event.

A

$S = {Mon, Tue, Wed, Thu, Fri, Sat, Sun}$

$E = {Sat}$

$Number of Outcomes equals 1$

B

$S = {Mon, Tue, Wed, Thu, Fri, Sat, Sun}$

$E = {Sat, Sun}$

$Number of Outcomes equals 2$

C

$S = {Mon, Tue, Wed, Thu, Fri, Sat, Sun}$

$E = {Sat, Sun}$

$Number of Outcomes equals 3$

D

$S = {Mon, Tue, Wed, Thu, Fri, Sun}$

$E = {Sun}$

$Number of Outcomes equals 1$
