n(S)=100

i)Let A be the event of getting a perfect square

A={1, 4, 9, 16, 25, 36, 49, 64, 81, 100 }

n(A)=10

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

=10/100

=1/10

ii)Let B be the event of getting not a perfect cube

perfect cubes={1,8,27,64}

so,n(B)=100-4

=96

p(B)=n(B)/n(S)

=96/100

=48/50

=24/25

hope helps mark as brainliest plz

give thanks
