Question

What is probability of numbers divisible by 4 from 1-200

Answer 1

Answer:

probability=4÷200=1/50

Answer 2

T.O.=200-1+1

      =200

Now by AP we can find the No. of favorable outcomes.

an=200 a=4 d=4

200=4+(n-1)4

196/4=n-1

49+1=n

50=n

Now,

P(E)= No of F.O./T.O.

     =50/200

      =1/4
