In 2005 there were 74,250 car accidents. In 42,197 of them, speed was a factor. Based on this, what is the probability that speed was a factor in an accident

Answer: The probability is 0.57

Step-by-step explanation: The number of possible outcomes according to the question are 74250 car accidents. What the question requires is that speed was a factor in an accident, and that is the required outcome. The number of required outcomes are 42197 (that is, accidents that occurred as a result of speed).

The probability that a car accident was due to speed can be expressed as follows;

P (Speed) = Number of required outcomes/Number of possible outcomes

P (Speed) = 42197/74250

P (Speed) = 0.5683

Approximately, this is 0.57

Therefore, the probability that speed was a factor is 0.57 (or 57%)
