| Professors meeting for the 1st time |

 | Hi Professor Holmes, my name is Bolt and I am a statistic professor. | |

| Professors talking about school |
|
| I just left school and now I need to grade my student's probability tests. | |
|
| I wonder how your students did, mine did horrible! I am so disappointed. | |

|
| I gave my class 2 tests. 25% of the class passed both of them and 42% of the class passed the 1st one. I wonder what percentage of the class passed the first test also passed the second test? | |
|
| Thats easy! 0.25/0.42 = 0.60 or 60%. So 60% of your students passed the 1st and 2nd test. | |
