Solution
There are 100 cards from which one card is drawn.
Total number of elementary event -n(s)-100
From number 1 to 100, there are 16 numbers which are multiple of 6 i.e.{6,12,18,24,30,36,42,48,54,60,66,72,78,84,90,96}
favorable number of event =n(E)=16
Probability of seleting card with a multiple of 6=
`(n(E))/(n(s))-16/100-4/25`
