Answer:
The probability that Johnny caught a smallmouth bass is C. 1/4.
Explanation:
The amount of largemouth bass is 3 times as many as the smallmouth bass, so, therefore, assuming there is 1 smallmouth bass, there would be 3 largemouth bass. The total number of bass is the number of largemouth bass added to the number of smallmouth bass, which is 4. Therefore, our whole (denominator) would be 4. Since there is 1 smallmouth bass in a group of 4 bass total, the probability is 1/4.
