Answer: "A. 3/8"
Step-by-step explanation:
STEP 1: Determine the probability the spinner lands on a multiple of 3. To do this, write out the numbers on the spinner (1-8), and cross out every non-multiple of three (1, 2, 4, 5, 7, 8), this will leave the numbers 3 and 6 unmarked. This being said, 2/8 (1/4) of the numbers on the spinner are multiples of 3.
STEP 2: Determine the probability the spinner lands in a dark green region. In order to do this, write the numbers on the spinner out (1-8), and circle every number representing a dark green region (1, 3, 5, 7). This should leave four numbers (2, 4, 6, 8) un-circled, meaning 4/8 (1/2) of the numbers represent a dark green region.
STEP 3: Add the two answers together (1/4 + 1/2), and you should get the answer 3/8 (A).
NOTE: When adding fractions, make sure they have the same denominators. For example, in this problem, changing 1/2 to 2/4, and doing 1/4 + 2/4, instead of 1/4 + 1/2.
