Question

On a 4 sided dice what is the probability that a 1 was rolled?

Answer (round) to the hundredth place value.

Answer 1

Given:

A 4 sided dice is rolled.

To find:

The probability of getting 1.

Solution:

A 4 sided dice is rolled.

On a 4 sided dice, the possible outputs are 1,2,3,4.

Total number of outcomes = 4

Favorable outcomes or number of 1 = 1

Now,

`\text{Probability of getting 1}=\frac{\text{Favorable outcomes}}{\text{Total number of outcomes}}`

`\text{Probability of getting 1}=(1)/(4)`

`\text{Probability of getting 1}=0.25`

Therefore, the probability of getting 1 is 0.25.
