#### Question

A bag contains 100 identical marble stones which are numbered 1 to 100. If one stone is drawn at random from the bag, find the probability that it bears:

a number divisible by 4

#### Solution

Total number of possible outcomes=100

Number which are divisible by 4=4,8,12,16,20,24,28,32,36,40,44,48,52,56,60,64,68,72,76,80,84,88,922,96,100

Number of favorable outccomes=25

p(number divisible by 4)=`25/100=1/4`

Is there an error in this question or solution?
