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`
