Answer:
1) 28.6%
2) 78.6 %
3)
(a) 75%
(b) 25%
Explanation:
1)
14 total blocks.
4 red blocks
Probability that the block is red:
[tex]\frac{4}{14}[/tex] = 0.286 = 28.6%
2)
There are 3 yellow blocks.
14 total blocks - 3 yellow blocks = 11 blocks that are not yellow
Probability that the block is not yellow:
[tex]\frac{11}{14}[/tex] = 0.786 = 78.6%
3)
(a)
The word or means that you need to add the probabilities together.
63 + 12 = 75%
(b)
Probability that Joe Starr will sign with the Yankees or the Dodgers is 75%.
If Joe Starr signs with a team other than the Yankees or the Dodgers, you need to subtract 75 from 100
100 - 75 = 25%
