A is your answer. The box is your IQR of 5-8.5, your median is 7, and your range is 2-10
        
             
        
        
        
Probabilities are used to determine the chances of an event
- The probability of choosing a black counter is 0.6
- The probability that both counters are white is 0.16
<h3>(a) Probability of selecting two blacks</h3>
The probability is given as:

Apply probability formula

Express as squares

Take the square root of both sides

Hence, the probability of choosing a black counter is 0.6
<h3>(b) Probability of selecting two white counters</h3>
In (a), we have:

Using the complement rule, we have:

So, we have:

Evaluate

The probability that both counters are white is then calculated as:

So, we have:


Hence, the probability that both counters are white is 0.16
