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
