Question

Ticket number 1 to 20 Are mixed up and then a ticket is drawn at random what is the probability that the ticket drawn at random has multiple of 4 or 5

Answer 1

Answer:

multiples of 4=5

multiples of 5=4

Answer 2

Step-by-step explanation:

n(S)= 20

let A be the event that the ticket drawn at random has multiple od 4 or 5

n(A) = {4,8,12,16,20} therefore n(A)= 5

P(A)=n(A)/n(S)

5/20

P(A) =4
