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: 

a multiple of 6

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`  

 

  Is there an error in this question or solution?
