Answer 2

Answer:

1,2,3,4,5,6,7,8⟶ Chances of arrow.

Total no. of possibilities =8.

A. B?

Only once it can point at 8.

∴ Probability= 1/Total no. of possibilities

= 1/8

B. An odd number ?

Odd numbers are 1,3,5,7

Therefore 4 possibilities.

Probability= Probability= 4/Total = 4/8 = 1/2

C. A number greater than 2?

Hence, numbers greater than 2 are,

3,4,5,6,7,8⟶6 chances.

Probability= 6/8 = 3/4

D. A number less than 9?

Here all are less than 9.

Hence no. of chances=8

Probability= 8/8 =1
