Question

When a ludo die is thrown once what is the probability of getting the number which is neither prime nor composite

Answer 1

There are 6 possible outcomes::----
1...2..3..4..5...6
Favourable:---2(only 4and6)
p=1/3

Answer 2

Answer: Our required probability is $\frac{1}{6}$

Step-by-step explanation:

Since we have given that

Number of possible outcomes of a die = 6

Outcomes are as follows:

$\{1,2,3,4,5,6\}$

We need to find the probability of getting the number which is neither prime  nor composite.

And we know that "Number which is neither prime nor composite " = 1

So, Probability of getting the number which is neither prime nor composite is given by

$\frac{\text{ Number of favourable outcomes}}{\text{ Total number of outcome}}\\\\=\frac{1}{6}$

Hence, our required probability is $\frac{1}{6}$
