Step-by-step explanation:
There are 14 green, 12 orange and 19 purple tennis balls in the bag,
[tex]14+12+19=45[/tex] balls in total.
A. The propbabilities that
a randomly chosen ball from the bag is green [tex]=\dfrac{14}{45};[/tex]
a randomly chosen ball from the bag is orange [tex]=\dfrac{12}{45}=\dfrac{4}{15};[/tex]
a randomly chosen ball from the bag is purple [tex]=\dfrac{19}{45}.[/tex]
A probability model for choosing a tennis ball from the bag is
[tex]\begin{array}{lccc}\text{Ball}&\text{Green}&\text{Orange}&\text{Purple}\\ \\\text{Probability}&\dfrac{14}{45}&\dfrac{4}{15}&\dfrac{19}{45}\end{array}[/tex]
B. Suppose a tennis ball is randomly selected and then replaced 75 times. You can expect that orange ball appear
[tex]\dfrac{4}{15}\times 75=4\times 5=20[/tex] times
