The value of P(R = 3) is 0.2854
<h3>Probability</h3>
Probabilities are used to determine the chances of events.
The given parameters are:
- --- the number of slots
- . --- the number of red slot
- . --- the number of black slot
- . --- the number of green slot
<h3>Individual probabilities</h3>
The probability that the ball lands on a red slot is calculated as:
Simplify
The probability that the ball does not land on a red slot is calculated as:
Simplify
<h3>
Binomial probability</h3>
The value of P(R = 3) is then calculated using the following binomial probability formula
Where:
So, we have:
Hence, the value of P(R = 3) is 0.2854

Answer:
Step-by-step explanation:
we know that
by the sum of interior angles of a triangle
so we have
we can simplify
and now we find the other angles
