what percentage of the people surveyed have basketball shoes?
a. 40%
b. 46%
c. 60%
d. 54%

Explanation:

Step1: Calculate the relative frequency of having basketball shoes

The relative frequency of having basketball shoes is the sum of the relative frequencies of having basketball shoes and running shoes (0.18) and having basketball shoes and no running shoes (0.28).
$$0.18 + 0.28$$

Step2: Perform the addition

$$0.18+0.28 = 0.46$$

Step3: Convert to percentage

To convert the relative frequency (0.46) to a percentage, multiply by 100.
$$0.46\times100 = 46\%$$

Answer:

B. 46%
