Question 12 (i)
A game of chance consists of spinning an arrow which comes to rest pointing at one of the numbers 1, 2, 3, 4, 5, 6, 7, 8 (see figure) and these are equally likely outcomes. What is the probability that it will point at 8?

Solution

Out of 8 numbers, an arrow can point any of the numbers in 8 ways.
$∴$ Total number of outcomes = 8
Favourable number of outcomes (arrow points at 8) = 1

Hence, P (arrow points at 8)
$= \frac{F a v o u r a b l e n u m b e r o f o u t c o m e s}{T o t a l n u m b e r o f o u t c o m e s} = \frac{1}{8}$
