number (ii) a number less than 14 (iii) a number which is a perfect square (iv) a
prime number less than 20.(v) an odd number.​

Answer 1

Step-by-step explanation:

1)Number on cards are 2 to 101

Even number are 2,4,6,..,100=50

Probability that it's an even number =50/100=1/2

2)Numbers less than 14 are 2,3,4,5,6,7,8,9,10,11,12,13=12

Probability=12/100=3/25

3) Perfect square are=4,9,16,25,36,49,64,81,100=9

Probability=9/100

4) Prime number less than 20 are 2,3,5,7,11,13,17,19=8

Probability=8/100=2/25
