If three different deaths are randomly selected without replacement, find the probability that they all involved intoxicated drivers ian Intoxicated? Yes Yes Intoxicated? No No 49 47 27 The probability is (Round to six decimal places as needed) Is such an event unlikely? A. No, because its probability is less than 0 05 B.

No, because its probability is greater than 005 )More Click to select your answer(s)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.
