Given that ellen has music practice three days a week. She practices for all of the three days 85% of the time, two days 8% of the time, one day 4% of the time, and no days 3% of the time. One week is selected at random.
The main objective is to construct a probability distribution table for the data.
Step-by-step explanation
Step 1.
Let X be the random variable that describes the number of days Ellen has music practice in a week.
Let be the probability that she practices for X number of days in a week.
From the given data, she practices for all of the three days 85% of the time, two days 8% of the time, one day 4% of the time, and no days 3% of the time.
Then the required the probability distribution table for the data is shown below:
