If a bag contain 100 marked cards so
.,
|S|=Sample space
=100
(one card is drawn at random)
|E1|= Event of getting a single digit
number
=9. (1,2,3,4,5,6,7,8,9)
P|E1|=9/100
|E2|=Event of getting a perfect square number
=9
(4,9,16,25,36,49,64,81,100)
P|E2|=9/100
|E3|=Event of getting a number divisible by 7
=.14 (7,14,21,28,35,42,49,56,63,70,77,84,91,98)
P|E3|=14/100
=7/50
