Explanation / Answer

Number of accidents involving intoxicated drivers = 25 + 49 = 74

Total number of accidents = 148

=> Probability of an accident involving intoxicated drivers = 74 / 148 = 0.5

=> The probability that three different accidents involved intoxicated drivers = (0.5)3

= 0.125

or 0.125000.

The event has probability > 0.05 and is therefore not unlikely.

The answer is D. No, because it's probability is greater than 0.05.
