Question

tickets numbered from 1 to 20 are mixed and keep it in a bag what is the probability of getting a number divisible by 5 at a random draw​

Answer 1

Step-by-step explanation:

Since, total tickets = 20

Multiples of 3 or 7 from 1 to 20 are:

3,6,7,9,12,14,15,18

∴ favorable outcomes=8

∴ required probability =

8/20 =2/5

Answer 2

Answer:

5

Step-by-step explanation:

As the probability is no of possible out comes by total no of out comes

then 1-20 are tickets so divisible by five 5,10,15,20

so there r 4 no so 4/20

= 5
