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? Select one:
a. 0.40
b. 0.50
c. 0.20
d. 0.30

Answer 1

║⊕ANSWER⊕║

Total number of tickets = 250

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:

0.4

Total no of outcomes=250

total favourable outcomes(ranging from 200 to 299)=100

Required probability=100C1/250C1 =0.4
