Question

a die ia thrown.find probability of getting either a prime no.or an even no.​

Answer 1

Answer:

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

n(S) = 6

event a = getting a prime no.

a = { 2,3,5 }

n(A) = 3

p(A) = n(a)/n(s)

p(A)= 3/6

p(A)= 1/2

event b = getting an even no.

B = { 2,4,6 }

n(b) = 3

p(b) = n(b)/n(s)

p(b) = 3/6

p(b) = 1/2
