Question

question 6
after giving a test to a group of students, the grades and gender are summarized below.

	a	b	c	total
female	9	3	12	24
total	28	7	18	53

round probabilities to 4 decimal places.

if one student is chosen at random,

find the probability that the student was male:

Explanation:

Step1: Identify total number of students

The total number of students is 53 (from the bottom - right cell of the table).

Step2: Identify number of male students

The number of male students is 29 (from the 'Male' row and 'Total' column).

Step3: Calculate probability

The probability $P$ of choosing a male student is the number of male students divided by the total number of students. So $P=\frac{29}{53}$.

Answer:

0.5472
