Question

A box contains 4 green tiles numbered 1 to 4. One tile is selected at random. What is the theoretical probability of drawing a 3?

WRITE YOUR ANSWER AS A DECIMAL

Answer 1

The answer Is 1/4 as a fraction and 0.25 as a decimal.

to find the probability of drawing 3 out of the 4 tiles we use the following formula:

Probability = successful outcomes / total outcomes

so in this case is P(Tile 3) = 1 out of 4 outcomes so P(Tile 3) = 1/4

to turn the fraction into a decimal we just divide the number on top of the fraction by the one on the bottom which should give us 0.25 as our final answer.

Answer 2

0.25

Explanation:

The four tiles are :

1

2

3

4

The probability of picking a 3 is one out of four = 1/4 = 0.25
