Question

In a recent year, 83,600 U.S. passenger cars rolled over when they crashed and 5,127,400 passenger cars did not roll over when they crashed. What is the probability that a randomly selected passenger car crash DOES result in a rollover

Answer 1

Answer:

1.60% probability that a randomly selected passenger car crash DOES result in a rollover

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

Desired outcomes:

83,600 U.S. passenger cars rolled over when they crashed, so $D = 83600$

Total outcomes:

83,600 U.S. passenger cars rolled over when they crashed and 5,127,400 passenger cars did not roll over when they crashed. So $T = 83600 + 5127400 = 5211000$

What is the probability that a randomly selected passenger car crash DOES result in a rollover

$p = \frac{D}{T} = \frac{83600}{5211000} = 0.0160$

1.60% probability that a randomly selected passenger car crash DOES result in a rollover
