Answer:

1/3 (c) is correct answer

Answer 2

Step-by-step explanation:

The probability of getting a prime number in a single throw of a dice is

Solution :-

When a die is thrown, the possible outcomes are 1,2,3,4,5,6.

When a die is thrown, the possible outcomes are 1,2,3,4,5,6.Number of possible outcomes =6

When a die is thrown, the possible outcomes are 1,2,3,4,5,6.Number of possible outcomes =6P(E)=

When a die is thrown, the possible outcomes are 1,2,3,4,5,6.Number of possible outcomes =6P(E)= Number of possible outcomes

outcomesNumber of favourable outcomes

outcomes Let E be the event of getting a prime number.

outcomes Let E be the event of getting a prime number.Outcomes favorable to E are 2,3,5.

outcomes Let E be the event of getting a prime number.Outcomes favorable to E are 2,3,5.Number of favourable outcomes =3

outcomes Let E be the event of getting a prime number.Outcomes favorable to E are 2,3,5.Number of favourable outcomes =3P(E)=3/6=1/2

outcomes Let E be the event of getting a prime number.Outcomes favorable to E are 2,3,5.Number of favourable outcomes =3P(E)=3/6=1/2Hence the probability of getting a prime number is 1/2.
