Answer

Explanation:

Step1: Calculate total number of students

Add all values in the table. Total students = (4 + 3+12 + 10=29)

Step2: Calculate number of students who slept more than 6 hours

Add the values in the "Slept more than 6 hours" column. Students who slept more than 6 hours = (4 + 12 = 16)

Step3: Calculate the probability

Probability (P=\frac{\text{Number of students who slept more than 6 hours}}{\text{Total number of students}}), so (P=\frac{16}{29})

Answer:

(\frac{16}{29})
