. The probability of drawing a blue cube from a hat is 80%. What is the probability of drawing 4 blue cubes in a row

Given:

The probability of drawing a blue cube from a hat is 80%.

To find:

The probability of drawing 4 blue cubes in a row.

Solution:

Let E be the event of drawing a blue cube from a hat.

We need to find the probability of drawing 4 blue cubes in a row.

Let as consider each cube is replaced after being drawn. So, that probability of drawing a blue cube from a hat remains same.

Probability of drawing 4 blue cubes in a row is

Therefore, the required probability is 0.4096.
