Question

A dice is thrown once .Find the probability of a composite number

Answer 1

in a dice number 4 and 6 are composite numbers
then the favourable outcomes is 2
Probability of composite numbers = 2/6
= 1/3

Answer 2

Answer:

1/3

Step-by-step explanation:

Total outcomes on rolling a dice = {1,2,3,4,5,6} =6

Definition of Composite number:A composite number is a positive integer that can be formed by multiplying two smaller positive integers. Equivalently, it is a positive integer that has at least one divisor other than 1 and itself.

So, composite numbers on rolling a dice = {4,6} = 2

So, probability of a getting a composite number :

Total events = 6

Favorable events = {4,6} =2

So probability of a getting a composite number : $\frac{2}{6} = \frac{1}{3}$

Hence the probability of a composite number is 1/3
