Question

A stack of 30 science flashcards includes a review card for each of the
following: 10 insects, 8 trees, 8 flowers, and 4 birds.
What is the probability of randomly selecting an insect?

Answer 1

unlikely but possible. there’s more trees, flowers and birds cards altogether rather than the 10 insect cards
20:10 that doesn’t give it a good chance of getting picked.

Answer 2

The probability of randomly selecting an insect is 2/15.

What is probability?

It is a measure of happening or non happening of the outcomes of a random experiment.

Formula for probability

P(E) = number of favorable outcomes/Total number of outcomes

Where, P(E) is the probability of any event.

Let E be an event of selecting an insect.

According to the given question

We have

Total number of insects = 10

Total number of trees = 8

Total number of flowers = 8

Total number of birds = 4

Now, the total number of outcomes = 10 + 8 + 8 + 4 = 30

Total number of favorable outcomes = 4

Therefore,

The probability of selecting an insect = $\frac{4}{30} =\frac{2}{15}$
