The owner of a sushi restaurant looked over some recent orders. He noted how many yellowtail and salmon rolls had been ordered. What is the probability that a randomly selected sushi roll is not extremely spicy and does not contain salmon? Simplify any fractions.

Question

Yellowtail - Salmon
Not Spicy 6 8
A little Spicy 10 3
Extremely Spicy 4 6
16/37
17/37
11/37
20/37

Answer 1

The total number of non-spicy sushi rolls is 6 (yellowtail) + 8 (salmon) = 14.

The total number of sushi rolls that do not contain salmon is 6 (yellowtail) + 4 (yellowtail) = 10.

So the probability that a randomly selected sushi roll is not extremely spicy and does not contain salmon is 10/14 = 5/7 = 20/28 = 10/14 = 5/7 = 71.4% = 20/37.

Therefore, the correct answer is 20/37.
