A die is thrown once. Find the probability of getting a prime number.
उत्तर
Total outcomes of throwing a die once are 1, 2, 3, 4, 5, and 6
Total number of possible outcomes = 6
Since 2, 3and 5 are prime numbers.
Favourable outcome = 3
P (probability) = `"Number of favourable outcomes"/"Total number of possible outcomes"`
= `3/6`
= `1/2`
