Answer:

2. 22/35

3a. 0.24

3b. 0.84

3c. 0.54

3d. 0.73

Explanation:

2. There are 22 songs on albums 1 and 2, and 35 total songs. Thus the probability of randomly choosing a song from albums 1 or 2 is 22/35.

__

3. The sum of the probabilities of all possible mutually exclusive events is 1, so ...

a. p(blue) = 1 - p(any other color) = 1 - 0.76 = 0.24

b. p(not green) = 1 - p(green) = 1 - 0.16 = 0.84

c. p(green+yellow+blue) = p(green) +p(yellow) +p(blue) = 0.16 +0.14 +0.24 = 0.54

d. p(not(yellow+red)) = 1 - p(yellow+red) = 1 - 0.27 = 0.73
