Question

If a die is rolled one time find these probabilities of geeting a prime number

Answer 1

the provablities is 1/2

Answer 2

let S be the sample space..

S= {1,2,3,4,5,6}

n(S)=6

Event A : getting a prime number.

A={2,3,5}

n(A)=3

p(A)=n(A)/n(S)=3/6=1/2,,

p(A)=1/2

therefore probability of getting a prime number is 1/2.
