Example Question #1 : Proportions
The probability of an event is 3/11. Find the chance the event will not occur.
3/11
8/3
11/3
8/11
3/8
8/11
If the chance an event will happen is 3/11, that means there are 8 instances where the even would not occur out of every 11, giving us 8/11.
3 chances out of 11 = event
11 – 3 = 8
8 chances out of 11 = no event
