Probability is quite simple. In this case, you just need to find the total number of balls (28) and the total number of black balls (20) Now, create a ratio (20/28) Next, simplify it down to 5/7, and that is your answer. I hope that helps! :)

Answer:

Probability of drawing a black ball in one draw [tex]= \frac{5}{7} \\[/tex]

Step-by-step explanation:

The probability of drawing a black ball in one draw

[tex]= \frac{Number of black ball}{Total number of balls} \\=  \frac{20}{28} \\= \frac{5}{7} \\[/tex]
