Question

Hey guys, Can u plz tell me about this activity.. Please!!

Answer 1

There are 900 3 digits numbers between 100 and 900, so n(s) = 900

Multiples of 3 in 100 to 900 = 300, n(E) = 300

Probability that number written by divisible by him/her is divisible by 3 =    300/900

 = 1/3

Hope This helps!
