Question

The manager of an ice cream shop found that the probability of a new customer ordering vanilla ice cream is 7/19.What are the odds against a new customer ordering vanilla ice cream?

Answer 1

`(7)/(12)`

Step-by-step explanation:

Here, we want to calculate the odds given the probability

To get this, we have to divide the probability by 1 minus the probability

We have that as:

`1-(7)/(19)\text{ = }(19-7)/(19)\text{ = }(12)/(19)`

Now, we divide the probability by the above

We have that as:

`(7)/(19)*(19)/(12)\text{ = }(7)/(12)`
