Question

giving a test to a group of students, the grades and gender are summarized below

	a	b	c	total
female	5	10	13	28
total	8	12	20	40

if one student is chosen at random,
find the probability that the student was male and got a \a\.

Explanation:

Step1: Identify relevant values

The number of male students who got an 'A' is 3, and the total number of students is 40.

Step2: Calculate probability

The probability formula for an event is $P(E)=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$. Here, the probability $P$ that a student is male and got an 'A' is $P=\frac{3}{40}$.

Answer:

$\frac{3}{40}$
