If a student is chosen at find the probability of getting someone who is a regular or heavy drinker. Round your answer to three decimal places Regular Drinker | Heavy Drinker!Total !Non-drinker Man 135 Woman Total 187 21 214 A) 0.161 B) 0.094 C) 0.178 D) 0.581Explanation / Answer
(1) Sum of all the probability value should be equal to 1.
In option A and B, total sum is not equal to 1 where as in option A P(A) is negative which cannot happen.
In option C, sum of all the probability values is 1. So option C is correct.
(2) Sum of all the probability values = 1.11
Hence, it is not a probability model.
