Question

Cards numbered 2 to 101 are placed in a box. A card is selected at random from the box. Find the probability that the card selected has an odd number which is not less than 60.

Answer 1

Total Number of cards , N=100
No of Odd Numbers above 60 and below 101 = 61,63,65.......101
=(( 101-61)/2) +1
=21
Therfore probability that the card selected has an odd number which is not less than 60 = 21/100
=.21
