Step 1:  See the given figure and analyse the given information

GIVEN:  A game of chance spinning an arrow,which come to rest pointing

any of the number 1,2,3,4,5,6,7,8

So, total number of outcomes = 8

Step 2:  Determine the probability that it(arrow) will point at "8"

Favourable outcomes of getting 8 = 1

The probability of  pointing 8 = \frac{\text{Favourable outcome}}{\text{total outcomes}}

= \frac{1}{8}

Step 3: Find the probability that it will point at an odd number

List out the odd number = {1, 3, 5, 7}

Favourable outcomes of  pointing an odd number = 4

The probability that arrow will point at an odd number = \frac{\text{Favourable outcome}}{\text{total outcomes}}

=   \frac{4}{8}
