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

To solve for the other leg, you need to use Pythagorean theory.
The theory states that C^2 = A^2 + B^2
In your case, you have to solve for B.
C = 40 (hypotenuse) A = 24 (leg 1)
The formula rewritten for B is
Now, you can solve.
Therefore, B = 32.
So the second leg is 32 feet.
