Question

8 faced unbiased die being number 1 to 8 is rolled once what is the probability of obtaining a number divisible by 3​

Answer 1

Step-by-step explanation:

Given:-

8 faced unbiased die being number 1 to 8 is rolled once .

To find:-

What is the probability of obtaining a number divisible by 3?

Solution:-

Given that

Number of faces in the given die = 8

Sample space ={1,2,3,4,5,6,7,8}

Total number of possible outcomes = 8

Numbers which are divisible by 3 from 1 to 8

=3,6

Number of favourable outcomes = 2

We know that

Probability of an event P (E) =

Number of favourable outcomes/Total number of possible outcomes

=> 2/8

=> 1/4

Probability = 1/4

Answer:-

The probability of obtaining a number divisible by 3 is 1/4

Used formula:-

Probability of an event P (E) =

Number of favourable outcomes/Total number of possible outcomes
