Question

A dice is thowrn once ' what is the probability of getting odd primes

Answer 1

The no.of odd primes on a dice is 2
Probability=2/6=1/3

Answer 2

the odd prime numbers on the dice =  3, 5 
probability = number of favorable events / total number of events
the number of odd primes on the dice = 2 
⇒ probability of getting a odd prime number = $\frac{2}{6}$
⇒ $\frac{1}{3}$
∴ the probability of getting odd primes = $\frac{1}{3}$
