Someone help me please!

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:

= 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:

= 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%
