Independent Activity II
Number of Girls
Let X be a random variable giving the number of girls in a randomly selected three-
child family. Assuming that boys and girls are equally likely to be selected, illustrate
the probability distribution of a random variable X.
Independent Activity III
Rolling Two Dice
Using the sample space for rolling two dice, illustrates a probability distribution for
the random variable X representing the sum of the numbers that appear.
Independent Activity IV
Face Mask
Julia is a boutique shop owner in her town. Due to COVID-19 pandemic, wearing a
face mask of a person is required for their safety. Since there are limited stocks
available, she decided to start another business by making a face mask. She started
selling face masks from day 1 to day 10. The data she collected is shown in the table
below.
Illustrate a probability distribution of a random variable X showing the number of
face mask sold per day and its corresponding probabilities.
