. A bag contains fifteen cards bearing number 11, 12, 13, …, 25. A card is chosen at random from the bag. Find the probability that it bears (i) a prime number (ii) a number divisible by 2 (iii) a multiple of 5 (iv)an even number.

Answer 1

Answer:

1. 1/3

2. 7/15

3. 1/5

4. 7/15

Step-by-step explanation:

1. prime no = 11, 13, 17, 19, 23

  probablity = 1/3

2. no divisible by 2 = 12, 14, 16, 18, 20, 22, 24

      probablity = 7/15

3. no multiple of 5 = 15, 20, 25

    probablity = 1/5

4. an even no = 12, 14, 16, 18, 20, 22, 24

 probablity = 7/15
