Question

1. A box contains 45 discs, which are numbered from 1 to 45. If one disc is drawn at random from the box, find the probability that it will be
(i) a two-digit number
(ii) a number divisible
by 5.​

Answer 1

Answer:

Hey Mate,here is Ur answer.

we know that the total number of discs=90

i) Let A be the probability getting a 2 digit number

therefore

P(A) = 81/90 = 9/10

ii) Let B be the probability of getting a square number

therefore,

P(B) = 9/90 = 1/10

Hope it will help...
