Respuesta :

Answer:

1/4

Step-by-step explanation:

There are 80 students.

25 are girls and 55 are boys.

10 are foreigners and 70 are Nepalese.

62.5% are Nepalese boys.

This means that the number of Nepalese boys is:

62.5/100 * 80 = 50

There are 50 nepalese boys and so there are 20 nepalese girls.

The probability of selecting a Nepalese girl is therefore:

20 / 80 = 1/4
