Sports science researchers determined that, of those people who skateboard, 22% have never had an injury, 45% have had one injury, 18% have had two injuries, and 15% have had three or more injuries. What is the probability that a randomly chosen skateboarder has not had three or more injuries?

Answer
A
0.15
B
0.25
C
0.50
D
0.85

Explanation

The probability of having three or more injuries is 15%, or 0.15. The probability of not having three or more injuries is the complement: 1 − 0.15 = 0.85. So the correct choice is 0.85.
