Question

A game consists of a spinning arrow that comes to rest pointing at one of the numbers $1,2,3,4,5,6,7,8,9,10,11,12$; as shown below.
If the outcomes are equally likely, find the probability that the pointer will point at a number between $3$ and $11$.

Answer 1

We have,

Total number of possible outcomes $=12$

Favorable outcomes for a number between $3$ and $11$ are $4,5,6,7,8,9,10$

So. the number of favorable outcomes $=7$

Hence, P$($the pointer will be at a number between $3$ and $11)=7/12$
