Answer

Explanation:

Step1: Find total number of days

We sum up all the values in the table. $1 + 5+5 + 4=15$.

Step2: Find number of days with 1 - cup coffee and 6 - hour sleep

From the table, the number of days when she drank 1 cup of coffee and slept 6 hours is 5.

Step3: Calculate the probability

The probability $P$ is the number of favorable outcomes divided by the total number of outcomes. So $P=\frac{5}{15}=\frac{1}{3}$.

Answer:

$\frac{1}{3}$
