What is the probability that the fish chosen will be a trout if a fish tank contains 25 trout, 20 bass, 15 perch, and no other kinds of fish?

Answer 1

Abigail Allen

The probability of a single event is calculated as:

Probability (event A) = #"number of ways event A can occur" / "total number of possible outcomes"#

Therefore,

Probability (trout) = #25 / 60 = 41.7%#

The probability of choosing a trout from the fish tank can be calculated by dividing the number of trout by the total number of fish in the tank.

Total number of fish in the tank = 25 (trout) + 20 (bass) + 15 (perch) = 60 fish

Probability of choosing a trout = Number of trout / Total number of fish = 25 / 60 = 5/12

So, the probability that the fish chosen will be a trout is ( \frac{5}{12} ) or approximately 0.4167.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
