Question

Number from 1 to25 are written on 25 separate cards .a card is drawn without looking it . What is probability of getting a) a number greater than 6
b)a number less than 15 c)an odd number d)a two digit number

Answer 1

Step-by-step explanation:

1. a) probability of getting a number greater than 6 is 19/25.
2. b) probability of getting a number less than 15 is 14/25
3. c) probability of getting an odd number is 13/25
4. probability of getting a two digit number is 16/25

Answer 2

Answer:

a) 0.76

b)0.56

c) 0.52

d) 0.64

Step-by-step explanation:

a) numbers greater than 6 are 7,8,9,...,25 = 19 numbers

probability = no. of possibilities ÷ total numbers of possibilities

probability = 19 ÷ 25 = 0.76

b)number less than 15 are 14,13,12,...,1 = 14 numbers

probability = 14 ÷ 25 = 0.56

c)an odd number

odd numbers are 1,3,5,7,9,11,13,15,17,19,21,23,25 = 13 numbers

probability = 13 ÷ 25 = 0.52

d) a two digit number

two digit numbers are 10,11,12,...,25 = 16 numbers

probability = 16 ÷ 25 = 0.64
