Question

A ticket is drawn at random from a bag containing tickets numbered from 1 to 40 . Find probability that the selected ticket has a number which is multiple of 7 and which is multiple of 5

Answer 1

probability that ticket is the multiple of 7= 5/40 i.e. 1/8


probability that ticket is the multiple of 5=8/40 i.e. 1/5

Answer 2

Answer:

The probability is 1/5

Step-by-step explanation:

Step 1:

Given Data

Total number of tickets in the bag=40

Number of Possible Events = 40

Numbers from 1 to 40 which are multiple of 5 are 5,10,15,20,25,30,35 and 40.

Step 2:

Number of tickets which has a number which is a multiple of 5=8

Probability =possible Events/Total Number of Outcomes

Step 3:

No. of possible events = 40

No. which r multiple of 5 are : 5,10,15,20,25,30,35,40.

No. of favorable events = 8

Therefore, required probability = 8/40 = 1/5
