Question

A dice is thrown once find the probability of getting prime number

Answer 1

no of prime numbers = m = 3 : { 2 ,3 ,5 }

total no of numbers  in a die = n = 6 

therefore m/n

= 3/6 

=1/2

Answer 2

Probability=favourable outcome /total outcomes

HERE
sample space or total outcomes= (1,2,3,4,5,6)=6
favourable outcome=(2,4,6)=3

so
Probability= 3/6=1/2
