Question

what is the probability of getting number 7 on rolling a fair dice​

Answer 1

If you do so you will find that the sum is 7 for 6 of the possible outcomes. Thus the sum is a 7 in 6 of the 36 outcomes and hence the probability of rolling a 7 is 6/36 = 1/6.

Answer 2

Concept

Probability is the measure of how likely something is to occur. When we're not sure how an event will turn out, we might talk about the probabilities of various outcomes—how likely they are. Statistics is the study of events that are guided by probability.

Given

Rolling a fair dice

Find

We are asked to determine what is the probability of getting number 7 on rolling a fair dice​

Solution

As we know there are

$1,2,3,4,5,6$

numbers which are showing on rolling a fair dice

So probability of getting number 7

= favorable outcomes/ Total number of outcomes

$\frac{0}{6} =0$

Hence the  probability of getting number 7 on rolling a fair dice​ is 0
