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: 

 between 40 and 60 

Solution

There are 100 cards from which one card is drawn. 

Total number of elementary event = n(s)=100   

From numbers 1 to 100, there are 19 number which are between 40 and 60 i.e. {41,42,43,44,45,46,4,748,49,50,51,52,53,54,55,56,57,58,59}  favourable number of event = n(E)=19 

Probability of selecting a cards between 40 and 60 

`= (n(E))/(n(S))-19/100`
