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?

Answer 1

Answer:

Step-by-step explanation:

There are to number of tickets are 250 from 101 to 350 number printed consecutively on them;

Out of total 250 tickets = 100 tickets have hundredth digit of 2 that is from 200-299;

To the probability  = 100/250 = 2/5

Answer 2

Answer:

The probability that a ticket selected at random (blindly) will have a number with a hundredth digit of 2 is $\frac{2}{5}$

Step-by-step explanation:

Tickets numbered consecutively from 101 through 350 .

Ticket numbers having 2 at hundredth place = 200 to 299 = 100 tickets

Total no. of tickets = 101 to 350 = 250

So, The  probability that a ticket selected at random (blindly) will have a number with a hundredth digit of 2 :

= $\frac{\text{Tickets have a number with a hundredth digit of 2}}{\text{Total no. of tickets}}$

= $\frac{100}{250}$

= $\frac{2}{5}$

Hence the probability that a ticket selected at random (blindly) will have a number with a hundredth digit of 2 is $\frac{2}{5}$
