Question

$15$ cards numbered $1,2,3,4,...,14,15$ are put in a box and mixed thoroughly. A man draws a card at random form the box. Find the probability that the number on the card is an even number.

Answer 1

We have,

Total number of cards $=15$

Even cards$=2,4,6,8,10,12,14$

Even card number$=7$

Probability of an even card$=\frac{7}{15}$

Hence, this is the answer.
