If there were a total of 100 raffle tickets sold and you bought 3 tickets, what's the probability that you'll win the raffle?
| 13% | |
| 19% | |
| 3% | |
| 8% |
You have 3 out of the total of 100 raffle tickets sold so you have a (\( \frac{3}{100} \)) x 100 = \( \frac{3 \times 100}{100} \) = \( \frac{300}{100} \) = 3% chance to win the raffle.

If the ratio of home fans to visiting fans in a crowd is 4:1 and all 38,000 seats in a stadium are filled, how many home fans are in attendance?
| 30,400 | |
| 25,500 | |
| 39,167 | |
| 29,167 |
A ratio of 4:1 means that there are 4 home fans for every one visiting fan. So, of every 5 fans, 4 are home fans and \( \frac{4}{5} \) of every fan in the stadium is a home fan:
38,000 fans x \( \frac{4}{5} \) = \( \frac{152000}{5} \) = 30,400 fans.
16 members of a bridal party need transported to a wedding reception but there are only 3 4-passenger taxis available to take them. How many will need to find other transportation?
| 4 | |
| 8 | |
| 5 | |
| 7 |
There are 3 4-passenger taxis available so that's 3 x 4 = 12 total seats. There are 16 people needing transportation leaving 16 - 12 = 4 who will have to find other transportation.
