Practice makes perfect
Probability is calculated by dividing the number of favorable outcomes by the number of possible outcomes.
P=Number of favorable outcomes/Number of possible outcomes
When Augustine is going to select his locker there are 535 lockers left, and 1 of them is the haunted locker. With this information we can calculate the probability of getting that locker.
P=1/535= 0.00186...
The probability of Augustin getting the haunted locker is about 0.186 %, so he should chill his beans.
