A probability experiment has two steps. There are two possible results for the first step, call them "A" and "B". If the result for the first step was "A", then there would be 5
Possible results for the second step. If the result for the first step was "B", then there
Would be 12 possible results for the second step. How many possible outcomes are there
For this experiment?
A) 60
B) 17
C) 8
D) 12

Question

Quizplus · Accepted Answer

The total number of possible outcomes is the sum of the outcomes from each branch of the first step: 5 outcomes when the first step is "A" and 12 outcomes when the first step is "B". Therefore, the total number of possible outcomes is 5 + 12 = 17.
