Question

a box contains cards numbered from 1 to 100 if one card is drawn at random find the probability of getting a square numbers to 2 digit numbers multiple of 8 ​

Answer 1

Answer:

the probability of getting two digit number will be 91 /100 and the probability of getting the multiple of 8 card is 12/100

Answer 2

Probability of getting 2 digit number is 0.9

Probability of getting a square numbers is 0.06.

Probability of getting multiple of 8 is 0.12.

Step-by-step explanation:

Total number of cards = 100

2 digit numbers cards = 90

2 digit square numbers = 16, 25, 36, 49, 64, 81  (6 cases)

numbers that are multiple of 8  = 12

Probability of getting 2 digit number = $\frac{90}{100}= \frac{9}{10}$

                                                             or 0.9

Probability of getting 2 digit square number = $\frac{6}{100}= \frac{3}{50}$

                                                                         or 0.06

Probability of getting multiple of 8 = $\frac{12}{100} = \frac{3}{25}$

                                                        = 0.12

Probability of getting 2 digit number is 0.9

Probability of getting a square numbers is 0.06.

Probability of getting multiple of 8 is 0.12.
