Question

In your dresser are five blue shirts, three red shirts,

and two 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?

Answer 1

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.

Answer 2

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

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

`(3)/(5+3+2) =(3)/(10)`

Answer:
`(3)/(10)` 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

`((5+3+2)-2)/(5+3+2) =(10-2)/(10) =(8)/(10)=(4)/(5)`

Answer:
`(4)/(5)` or 80%
