Question

a die is thrown once then what is the probability of getting a composite number?

Answer 1

Favorable outcomes=2 ( 4, 6)
Total outcomes= 6
 P(E)=Favorable outcomes/ Total no. of outcomes
=2/6
=1/3

Answer 2

Answer:

$\frac{1}{3}$

Step-by-step explanation:

Numbers on dice = {1,2,3,4,5,6}

Composite numbers : A whole number that can be made by multiplying other whole numbers except 1 and itself.

So, 4 and 6 are composite numbers on dice .

Probability of getting an event = $\frac{\text{favorable outcome}}{\text{Total Outcome}}$

We are supposed to find the probability of getting a composite number on dice.

Favorable outcome = {4,6}=2

Total outcome = 6

Probability of getting a composite number = $\frac{2}{6} =\frac{1}{3}$

Hence the probability of getting a composite number is $\frac{1}{3}$.
