The digits 0, 1, 2, 3, 4, 6 are used to make 3 digit code. What is the probability that code is a number, not less than 200 and divisible by 5 if repetition of the digit is allowed?

(A) 0.43
(B) 0.16
(C) 0.19
(D) 0.11
(E) 0.51


Answer: (D)

Explanation:

Total code possible are,
= 6 * 6 * 6
 
Greater than 200 and divisible by 5, 
= 4 * 6 * 1

Required Probability,
= (4 * 6 * 1) / (6 * 6 * 6) 
= 1 / 9 
= 0.11 

So, option (D) is correct.
