Question

Hundred identical cards are numbered from 1 to 100. The cards The cards are well shuffled and then a card is drawn. Find the probability that the number on card drawn is:

less than 48

Solution

There are 100 cards from which one card is drawn.

Total number opf elementry event =n(s)=100

From number 1 to 100, there are 47 number which are less than 48 i.e. (1,2,................46,47) favorable number of event  =n(E)=47

Probabilty of selecting a card with a number less than 48=

(n(E))/(n(s)) -47/100

Is there an error in this question or solution?
