Question

In a charity show tickets numbered consecutively from $101$ through $350$ are placed in a box. What is the probability that a ticket selected at random (blindly) will have a number with a hundredth digit of $2?$

• A. $0.40$
• B. $0.50$
• C. $0.35$
• D. $0.20$

Answer 1

Answer: (A)

$0.40$

Total numbers: $250$

Total number with ${100}^{th}$ digit as $2$ are: $100\to 299-199=100$

Required probability:

$P=\frac{100}{250}=\frac{2}{5}$
