Answer:

a) A multiple of 4 - ⅕

b) A 1 digit number - ⅗

c) An odd number - ⁸/₁₅

d) A number not greater than 6 - ⅓

e) A number which is not less than 8 - ⁷/₁₅

Step-by-step explanation:

a) From numbers 1 - 15 the multiples of 4 are -- 4, 8, 12

So,

Count Of Number Which Are Multiple Of 4

Total Number Given

= 3/15 = 1/5

b) From numbers 1 - 15 all 1 digit numbers are -- 1, 2, 3, 4, 5, 6, 7, 8, 9

So,

Count Of Number Which Are 1 Digit

Total Number Given

= 9/15 = 3/5

c) From numbers 1 - 15 all odd numbers are -- 1, 3, 5, 7, 9, 11, 13, 15

So,

Count Of Odd Numbers

Total Number Given

= 8/15

d) From numbers 1 - 15 all numbers which aren't greater than 6 are -- 1, 2, 3, 4, 5

So,

Count Of Number Which Aren't Greater Than 6

Total Number Given

= 5/15 = 1/3

e) From numbers 1 - 15 all numbers which aren't less than 8 are -- 9, 10, 11, 12, 13, 14, 15

So,

Count Of Number Which Aren't Less Than 8

Total Number Given

= 7/15
