There are two Geometry classes at a high school. Two students are being picked to attend a special math competition, one student from each class. If there are 20 students in one class and 26 students in the other, find the probability of being picked to attend the competition

The probability from the first class is 1/20, and the probability from the second class is 1/26......

Answer:

1/23

Step-by-step explanation:

First you find the individual probabilities!

20 Class = 1/20 probability

26 Class =1/26 probability

Since you are trying to find the probability for both probabilities together, you add your probabilties together.

1/20 + 1/26 = 2/46

Next, we need to reduce this fraction.

To do this, lets divide this by 2.

2 ÷ 2 = 1 and 46 ÷ 2 = 23

This gives us the answer of 1/23
