Mathematics
1 answer:
Bad White [126]3 years ago
5 0

Answer:

41/293

Step-by-step explanation:

You have to be a little careful with the denominator. It must be the total of the columns which is the same total for the rows -- 586

The numerator is just the intersection of rats and Ravenclaw which is 82

So the answer is 82/586

The answer is also 41 / 293

In case you want the decimal it is .1399 rounded.
