C. 45%
D. 43%

Answer 1

The probability that Jamie buys a telecaster or a Less Paul is 45% or forty-five percent.

How to find out the probability?

1. Find the individual probabilities:

Probabilities to buy a telecaster:

• 1/ 4 = 0.25

Probabilities to buy a Les Paul:

• 1/ 5 = 0.2

2. Add the probabilities:

• 0.25 + 0.2 = 0.45

3. Multiply by 100:

• 0.45 x 100 = 45%
