Question

11. A box contains cards marked with numbers 5 to 20 A card is drawn from the bag
random Find the probability of getting a number which is a perfect square​

Answer 1

Answer:

Probability of getting a number which is a perfect square is 2 / 15.

Step-by-step explanation:

Given:

Box contains cards marked from numbers = 5 to 20

Numbers that is a perfect square between 5 and 20 = 9 and 16

Formula for finding probability of an event = No of favorable outcomes / Total No of Outcomes

Number of Favorably outcomes = 2 (As there are only two perfect squares between 5 and 20)

Total number of outcomes is the numbers that are in between 5 and 20.

Total number of outcomes = 20 - 5 = 15

Probability of the event = No of favorable outcomes / Total No of Outcomes

= 2 / 15

Therefore, Probability of getting a number which is a perfect square is 2 / 15.
