Cards marked with numbers 2 to 101 are placed in a box and mixed thoroughly. one card is drawn from this box. find the probability that the number on the card is a) a number less than 14 b) a number which is a perfect square

number of cards = 100

number less than 14 = {2,3,...,13} = 12

number perfect square = {4, 9, 16, 25, 36, 49, 64, 81, 100} = 9

so

a) probability = 12/100 = 3/25

b) probability = 9/100

Answer 3/5 and decimal .6

Step-by-step explanation:A^2+B^2=C^2

A-^2+ 20^2= 25^2

A^2+ 400= 625

Subtract 400 A^2= 225

A= 15 since sq rt of 225 is 15
