Question

15 cards numbered 1,2,3,4,5,6,7,8,9,10,11,12,13,14,15 are put in a box and mixed thoroughly . A man draws a card at random from the box . find the probability that the number on the card is 1.a number divisible by 2or3 ​

Answer 1

Answer:

The number of cards are = 15 (1,2,3... 15)

Now, the number divisible by both 2 and 3 is = 6 and 12

Now,

Favorable outcome = 15 (1,2,3... 15)

Possible outcome = 2 (6, 12)

probablity =

$= \frac{favorable \:outcome }{possible \: outcome} \\ = \frac{2}{15}$

mark me as brainliest plz.....
