Answer 1

Answer:

s=(1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20)

n(s)=20

A=(4,8,12,16,20)

n(A)=5

Answer 2

Answer:

S = (1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20 )

Now n(S)=20

Let A be the event that the number got is multiple of 4

A=(4,8,12,16,20)

n (A)=5

So, p (A)= n (A)/n (S)

=5/20

= 1/4

so the probablity of getting multiple of 4 is1/4
