in a class of 20 students, 14 are female and 7 have an a in the class. there are 4 students who are male and do not have an a in the class. what is the probability that a student chosen randomly from the class is a female?

Answer

Explanation:

Step1: Identify total number of students

The total number of students in the class is 20.

Step2: Identify number of female students

The number of female students is 14.

Step3: Calculate probability

The probability $P$ of choosing a female student is given by the formula $P=\frac{\text{Number of female students}}{\text{Total number of students}}$. So $P = \frac{14}{20}=\frac{7}{10}$.

Answer:

$\frac{7}{10}$
