Question

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

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%`
