Question

A box contain 90 dics which are numbered from 1 to 90. if one dics is drawn at random from the box .find the probability that is bears
(i) a two digit number
(ii) a perfect square number
(iii) a number divisible by 5
​

Answer 1

Answer:

Let E be the event of drawing a disc from the box of discs numbered from 1 to 90

Two digit numbers from 1 to 90=10,11,12,..,90

No. of favorable outcomes=81

Total no. of possible outcomes =90

We know that, Probability P(E) =

(Total no.of possible outcomes)

(No.of favor

=

90

81

=

10

9

Therefore, the proba.bility of a two digit numbered disc from the

5
