Question

Augustin is in line to chose a new locker at school. The locker coordinator had each student reach into a bin and pull out a locker number. There is one locker at the school that all the kids dread! This locker ,# 831, is supposed to be haunted , and anyone who has usde is has had strange things happen to him or her ! When it is Augustin's turn to reach into the bin and select a locker number ,he is very nervous . he knows there are 535 lockers left and locker #831 is one of them . What is the probability that Augustin reaches in and pulls out the dreaded locker #831? Should be worried ? Explain.

Answer 1

#831 is one out of the 535 left

1/535
= 0.002
= 0.2%

The probability is 0.2%, which is very low. It's even less than 1%. This means it's still very unlikely to get #831 and more like to get one of the other 534 numbers.
0.2% compared to 99.8%
If you look at these 2 numbers on a number line, you can see 99.8% (the other numbers) is more closer to 100%. This proves Augustin is more likely to chose one of the other numbers and doesn't have to be nervous.
