A post office sells stamps with 10 different images on them: flowers, trees, insects, birds, landscapes, constellations, frogs, mountains, fish, and bears. The post office has an equal amount of each stamp. One stamp is selected at random. Determine the theoretical probability of selecting a tree or frog stamp. Express your answer as a fraction in simplest form.

Respuesta :

Using the it's concept, it is found that the theoretical probability of selecting a tree or frog stamp is of 0.2 = 20%.

What is a probability?

A probability is given by the number of desired outcomes divided by the number of total outcomes.

A theoretical probability is calculated before experiments.

In this problem:

  • There is a total of 10 stamps.
  • Of those, 2 have tree or frog stamp.

Hence:

[tex]p = \frac{2}{10} = 0.2[/tex]

The theoretical probability of selecting a tree or frog stamp is of 0.2 = 20%.
