Answer:
Explanation:
Problem 2a
The total number of ways that he can deal with his room
is 3 * 2 * 3 = 18
Problem 2b
P(green, plaid, track) = 1/3*1/2*1/3 = 1/18
Problem 2C
The bedspread and the poster don't change. The word or in probability is a real stinker. In this case it means that there are 2 choices of paint color.
The only choice that won't work is if he chooses hospital white instead of green or blue. So he has a 2/3 chance of choosing one of the two colors he wants.
The probability then becomes P(bedspread,Poster, color) = 1/2 * 1/3 * 2/3 =
2/18
