question\nfor a certain class, the following data table summarizes the amount of sleep of students and whether or not they have an a in the class. what is the probability that a student chosen randomly from the class slept 6 hours or less?\n| |slept more than 6 hours|slept 6 hours or less|\n|--|--|--|\n|has an a|3|2|\n|does not have an a|9|16|

Answer

Explanation:

Step1: Calculate total number of students

$3 + 2 + 9 + 16 = 30$

Step2: Calculate number of students who slept 6 hours or less

$2 + 16 = 18$

Step3: Compute the probability

$\frac{18}{30} = \frac{3}{5}$

Answer:

$\frac{3}{5}$
