Answer:
total cards= 101-2=99+1=100
(a) even no. =(2,4,6,8,10,12,14,16,18,20,22,24,26,28,30,32,34,36,38,40,42,44,46,48,50,52,54,56,58,60,62,64,66,68,70,72,74,76,78,80,82,84,86,88,90,92,94,96,98,100)=50
p(E)=50 =1
100 2
(b)total cards=100
square no.=(1,4,9,16,25,36,49,64,81,100)=10
p(E)=10 = 1
100 10
