Determine the probability that the field of the student obtained is physical or social science.

Explanation / Answer

Dear student, I am only answering the first question as per Chegg Guidelines. Kindly post only one question at a time.

The sum of probabilities in the first table is 1 and none of the entries is greater than 1 or less than 0, therefore the first table is a probability distribution.

In both the other tables, sum is not equal to one.
