The ratio is the relationship of two numbers. Here is an example, you have 2 apples and 6 bananas. To compare the ratio between the apples and the bananas we create a ratio, so the ratio would be 2 to 6, or 2:6, or 2/6.
A rate is a little different than the ratio, it is a special kind of ratio. That is a comparison of measurements that have different units, like pounds and quarters.

Step-by-step explanation:
86 band members
26 are senior, 17 plays trumpet. If 4 are seniors and play trumpet, we solve this using the bayes theorem of conditional probability.
Probability of choosing band member that plays trumpet =17/86 = 2/43.
Probability of choosing a senior that plays trumpet = 4/26
Probability that a chosen member is a senior given that he plays trumpet = (2/43)/(4/26)
= 0.3023.
