Question

the probability that a number select from 1,2,3,4...19 and 20 will be a multiple of 5 _______​

Answer 1

Answer:

Let E be the event of getting a multiple of 5 from the data.

E = {5,10,15,20}, n(E) = {4}

n(s) = { 20 }

Probability of Event = n(E)/n(s)

= 4/20

= 1/5.

Therefore, 1/5 is the probability.
