Question

Fifty cards bearing numbers 1 to 50 are placed in a box.One card is drawn at random.A is the event that the number on the card is divisible by 13.Find n(A) ​

Answer 1

Answer:

No. of perfect square between 1 to 50 =7 (from 1

2

to 7

2

)

Therefore the probability that the card is drawn is a perfect square =

50

7

(b)No.of integers divisible by 6 between 1 to 50 =8 (from 6×1→6×8)

Therefore the probability that the card is drawn is divisible by 6 =

50

8

=

25
