उत्तर
There are 100 cards from which one card is drawn.
Total number of elementary events = n(S) = 100
From numbers 1 to 100, there are 47 numbers which are less than 48 i.e. {1, 2, ................, 46, 47}
Favorable number of events = n(E) = 47
Probability of selecting a card with a number less than 48
= `(n(E))/(n(S))`
= `47/100`
