Three biased coins are tossed.
Write down all the possible outcomes when the three coins are tossed.
Â
For each coin the probability of getting heads is . A random variable, X, is defined as the number of heads when the three coins are tossed.
Complete the following probability distribution table for X:
x | 0 | 1 | 2 | 3 |
 |  |  |  |
Â
 Hence, by inserting the relevant probabilities, represent the probability distribution for X as a
piecewise function in the form
Represent the probability distribution for as a bar chart.
