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

n(S) = {6}

★ event a = probability of getting number 5

A = { 1 }

$\sf \: n(P) = \frac{n(A) }{n(S) } = \frac{1}{6}$

★ event b = probability of getting an odd number

B = { 1, 3, 5 }

n(B) = {3}

$\: \sf \: n(P) = \frac{n( B) }{n(S) } = \frac{3}{6} = \frac{1}{2}$

★ event c = probability of getting a prime number

C = {2, 3, 5}

n(C) = {3}

$\: \sf \: n(P) = \frac{n( C) }{n(S) } = \frac{3}{6} = \frac{1}{2}$

★ event d = probability of getting multiple of 2

D = {2, 4, 6}

n(D) = {3}

$\: \sf \: n(P) = \frac{n( D) }{n(S) } = \frac{3}{6} = \frac{1}{2}$

$\sf \fbox \red{Ans :-} \: \: \: \: \: \: \: a = \frac{1}{6} \\ \sf \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: b = \frac{1}{2} \\ \sf \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:c = \frac{1}{2} \\ \sf \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:d = \frac{1}{2}$
