Each day the wildlife commission releases 100 fish into the Durkee river in the following proportions: 55 brown trout and 45 rainbow trout. All of the fish swim through a watch station, one at a time, on the way upstream. Which of the following expressions represents the way to calculate the probability of a passing fish being a rainbow trout?
(1) 45/55. (2) 45/100. (3) 55/100. (4). 55-45 over 100
(5) 45/55 over 100
I think it is 2
I'll be glad to check your answer.
Yes, 45/100
Thanks for checking homework
You're welcome.
To calculate the probability of a passing fish being a rainbow trout, we need to divide the number of rainbow trout by the total number of fish.
In this case, the number of rainbow trout is 45 and the total number of fish is 100. So the probability can be calculated as:
Probability = Number of Rainbow Trout / Total Number of Fish
Therefore, the correct expression to calculate the probability is (2) 45/100.
