Answer 1

Answer:

Solution(i):

Let E be the event of drawing a two digit number from the cards numbered from 2 to 90

Two digit numbers from 2 to 90=10,11,12,.....,90

No. of favorable outcomes=81

Total no. of possible outcomes =89

We know that, Probability P(E) =  

(Total no.of possible outcomes)

(No.of favorable outcomes)

​  

=  

89

81

​  

 

Therefore, the probability of a two digit number from the cards numbered from 2 to 90=  

89

81

​  

 

Solution(ii):

Let F be the event of drawing a perfect square number from the cards numbered from 2 to 90

Perfect square numbers from 2 to 90=4,9,16,25,36,49,64,81

No. of favorable outcomes=8

Total no. of possible outcomes =89

We know that, Probability P(F) =  

(Total no.of possible outcomes)

(No.of favorable outcomes)

​  

=  

89

8

​  

 

Therefore, the probability of drawing a perfect square number from the cards numbered from 2 to 90=  

89

8
