Answer:
87.5% probability that it is NOT number 2.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
Desired outcomes:
Any ball not numbered 2. So 1,3,4,5,6,7,8. So 7 desired outcomes, which means that [tex]D = 7[/tex]
Total outcomes:
All balls, which are 8. So [tex]T = 8[/tex]
Probability:
[tex]p = \frac{D}{T} = \frac{7}{8} = 0.875[/tex]
87.5% probability that it is NOT number 2.
