It is given that total number of females (*N*) is 49. Total number of females who get C grade (*n*) is 19.

Thus,

The probability that a female gets C grade, can be calculated as:

Step 2

Check the condition of normality,

if *Np *and *Np*(1-*p*) both are greater than 5, then it will follow normality.
