Answer:
<em>The probability is zero</em>
Step-by-step explanation:
<u>Probability</u>
There are 3 white counters and 2 black counters in a bag. One of them is chosen at random.
It's required to calculate the probability that a <u>green</u> counter has been chosen.
The probability of an outcome is defined as the frequency of the number of times the outcome occurs relative to the number of times that it could have occurred.
The equation to calculate the probability is:
Where f is the number of favorable cases and n is the total cases.
Since there are no green counters in the bag, it's impossible to choose a green counter, thus f=0 out of n=5 total cases:
P = 0
We have put the cross in the mark 0 on the probability scale below

Step-by-step explanation:
Justin's score has to be greater than 80. the appropriate inequality sign is >
Note that
> means greater than
< means less than
≥ means greater than or equal to
≤ less than or equal to
On the number line, since the score has to be greater than 80, the line would start from 80 and end on 95
> or < is represented by unfilled circle
≤ or ≥ is represented by filled circle
