Answer:
P(R or G) = 0.3
Step-by-step explanation:
We are given the following in the question:
x: BR Y R BL O G
P(x): 0.1 0.2 0.1 0.2 0.2 0.2
First, we check the nature of distribution.
[tex]\displaystyle\sum p(x) = 0.1 + 0.2 + .1 + 0.2 + 0.2+ 0.2 = 1[/tex]
Thus, it is a discrete probability distribution.
We have to evaluate P(R or G)
[tex]\text{P(R or G)} = P(R) + P(G) = 0.1 + 0.2 = 0.3[/tex]
Thus, the probability of selecting a red or a green M&M is 0.3
You can use the addition rule of probability to find out the probability of picking red or green almonds out of the specified bag.
The probability of picking red or green almonds out of the specified bag is 0.3
What is the addition rule of probability?
If in a probability experiment, there are two events A and B, then the probability of occurrence of A or B is given by
[tex]P(A \cup B) = P(A) + P(B) - P(A \cap B)[/tex]
How to use addition rule to get the probability of picking red or green almonds?
Let we have:
A = event of picking out red almonds
B = event of picking out green almonds
It is given that P(A) = 0.1 and P(B) = 0.2
Since both of them cannot be selected together as there is only 1 item picked out, thus, P(A∩B) = 0
Thus, from the addition rule of probability, we have
[tex]P(A \cup B) = P(A) + P(B) - P(A \cap B)\\P(A \cup B) = 0.1 + 0.2 - 0 = 0.3[/tex]
Thus, the probability of picking red or green almonds is given 0.3
