उत्तर
Total possible outcomes that occur after throwing a die once are 1,2,3,4,5,6
Number of possible outcomes = 6
We need to find the probability of getting a prime number
Prime number is a number not divisible by any number except itself
Prime numbers on dice are 2,3 and 5.
Number of favourable outcomes =3
Probability of getting a prime number = `" Number of favourable outcomes"/"Total number of possible outcomes"`
Probability of getting a prime number = `(3)/(6) = (1)/(2)`
