Possible outcomes = 8
Numbers that are factors of 8 = 1 , 2 , 4 , 8
So total 4 numbers
Probability = 4/8 = 1/2

Answer:
Ans. Out of 8 numbers, an arrow can point any of the numbers in 8 ways.
Total number of favourable outcomes = 8
(i) Favourable number of outcomes = 1
Hence, P (arrow points at 8) =
(ii) Favourable number of outcomes = 4
Hence, P (arrow points at an odd number) =
(iii) Favourable number of outcomes = 6
Hence, P (arrow points at a number > 2) =
(iv) Favourable number of outcomes = 8
Hence, P (arrow points at a number < 9) = =1
