Question

giving a test to a group of students, the grades and gender are summarized below grades vs. gender a b c male 6 13 19 female 18 14 8 if one student was chosen at random, find the probability that the student got a c. probability = (round to 4 decimal places)

Explanation:

Step1: Calculate total number of students

$6 + 13+19 + 18+14 + 8=78$

Step2: Calculate number of students who got a C

$19 + 8=27$

Step3: Calculate the probability

The probability $P$ of choosing a student who got a C is the number of students who got a C divided by the total number of students. So $P=\frac{27}{78}\approx0.3462$

Answer:

$0.3462$
