Answer

Explanation:

Step1: Calculate total number of students

$6 + 7+5 + 8=26$

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

$7 + 8 = 15$

Step3: Calculate the probability

Probability = $\frac{\text{Number of students who slept 6 hours or less}}{\text{Total number of students}}=\frac{15}{26}$

Answer:

$\frac{15}{26}$
