in a dresser are three blue shirts, seven red shirts, and six black shirts.
a) what is the probability of randomly selecting a red shirt?
b) what is the probability that a randomly selected shirt is not black?
a) the probability of randomly selecting a red shirt is
(type an integer or a decimal. do not round.)

Explanation:

Step1: Calculate total number of shirts

$3 + 7 + 6 = 16$

Step2: Find probability of red shirt

$\text{Probability} = \frac{\text{Number of red shirts}}{\text{Total shirts}} = \frac{7}{16} = 0.4375$

Step3: Calculate non-black shirt count

$3 + 7 = 10$

Step4: Find probability of non-black shirt

$\text{Probability} = \frac{\text{Number of non-black shirts}}{\text{Total shirts}} = \frac{10}{16} = 0.625$

Answer:

a) $0.4375$
b) $0.625$
