Question

Eric buys 13 raffle tickets for a trip to Las Vegas. The number of tickets sold for the event is 208. All the tickets are placed in a spinning contraption, and one ticket will be chosen at random. Find the probability of Eric's chances of winning the prize. Convert the fraction to a decimal. Round to three decimal places.

Answer 1

We know that Eric has 13 out of the 208 tickets that were sold in total.

When the tickets are spinning and one is pulled out, the ticket pulled out has the same chance to be one of the thirteen tickets Eric bought or any of the others.

As such, his chances of winning the prize are

`(13)/(208)=0.0625`

Round to three decimal places, his chances of winning are 0.063.
