- The probability of choosing a black counter is 0.6
- The probability that both counters are white is 0.16
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
