Question

Find the probability.When using a single die, what is the probability of rolling a number less than or equal to 6?A) 6B) 5C) 5/6D) 1

Answer 1

It is given that a single die is used.

It is required to find the probability of rolling a number less than or equal to 6.

Recall that the probability of an event is given by the formula:

$P=\frac{\text{ Number of favorable outcomes}}{\text{ Total number of possible outcomes}}$

The sample space of a single die is:

$\lbrace1,2,3,4,5,6\rbrace$

Hence, the total number of possible outcomes is 6.

The numbers less than or equal to 6 are:

$\lbrace1,2,3,4,5,6\rbrace$

Hence, the number of favorable outcomes is 6.

Substitute these values into the probability formula:

$\Rightarrow P=\frac{6}{6}=1$

The answer is D.
