black?

First, add all of the shirts together (5+3+2) which equals 10 shirts in total.

a) The probability of selecting a red shirt would be 3/10 or 30% chance.

b) The probability that a black shirt would not be selected would be 8/10 or 80% chance.

a) What is the probability of randomly selecting a red shirt?

-> Probability can be solved with wanted outcomes divided by total outcomes

[tex]\frac{3}{5+3+2} =\frac{3}{10}[/tex]

Answer: [tex]\frac{3}{10}[/tex] or 30%

b) What is the probability that a randomly selected shirt is not

black?

-> Probability can be solved with wanted outcomes divided by total outcomes

[tex]\frac{(5+3+2)-2}{5+3+2} =\frac{10-2}{10} =\frac{8}{10}=\frac{4}{5}[/tex]

Answer:  [tex]\frac{4}{5}[/tex] or 80%
