Question

A parachutist drops a penny from 1000 feet above the ground. What is the probability of the penny landing a 10 cm x 10 cm square inside a 1000 cm x 1000 cm square?

Answer 1

The total area where the penny can drop is:

`1000\cdot1000=1,000,000`

and the area were we want that the penny drop is:

`10\cdot10=100`

So the probabilitie will be:

`p=(100)/(1000000)=0.0001`

So the probabilitie is 0.01%
