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]
