Question

A box contains 10 cards marked with the numbers 1 to 10. One card is shown from this box at
random. What is the probability that number on the card is perfect square ?​

Answer 1

Answer:

4/5

Step-by-step explanation:

Total outcomes- 10

Possibility of not a perfect square from 1 to 10 = 8 (1,2,3,5,6,7,8,10)

(bcoz from 1 to 10 only 2 no. are perfect square which are 4 & 9, So 10-2= 8)

P(E) = No. of possible outcomes/ Total no. of outcomes

P(E) = 8/10

which will be- 4/5
