95 people were asked what type of soft serve ice cream they were most likely to buy. Their choices were vanilla, chocolate, and swirl (a combination of vanilla and chocolate). The chart shows the results. Which of the following statements are correct? There may be more than one correct answer.
| Vanilla | Chocolate | Swirl | Total | |
| Male | 6 | 22 | 9 | 37 |
| Female | 10 | 27 | 21 | 58 |
| Total | 16 | 49 | 30 | 95 |
- There is almost no difference in probability in choosing someone who likes vanilla, whether choosing from all people, only men, or only women.
- It is nearly equally likely that you will choose someone at random who likes swirl, whether choosing from all people, only men, or only women.
- It is more likely that you will choose a man from people who like swirl, than if you choose from people who like vanilla.
- Randomly choosing a woman from people who like vanilla is more likely than choosing a woman from people who like chocolate.
