Question

Tickets numbered 1 to 20 are mixed up and then a ticket is drawn at random. What is the probability that the ticket drawn has a number which is a multiple 5? Option 1 : 1/2 option :2/4 option 3: 1/5 option 4 :3/5

Answer 1

Answer:

4/20

Step-by-step explanation:

no of outcomes=20

no of favourable outcomes=4

outcomes=1,2,3,.......20

favourable outcomes=5,10,15,20

probability=no of favourable outcomes/total no outcomes

=4/20

=1/5

Answer 2

Answer:

A ticket is drawn from 1-20

n(s)=20C1

E be the event of selecting a multiple of 5.

E={5,10,15,20}

p(E)=n(E)/n(s)=4/20=1/5
