Answer:
The probability of selecting a red or green marble is 0.6923.
Step-by-step explanation:
Let's denote the events as follows:
<em>R</em> = a red marble is chosen
<em>G</em> = a green marble is chosen
The information provided is:
n (R) = 7
n (G) = 5
n (R ∩ G) = 3
Total number of marbles in the bag is, N = 13.
The probability of an event <em>E</em> is:
Compute the probability of selecting a red or green marble as follows:
P (R ∪ G) = P (R) + P (G) - P (R ∩ G)
Thus, the probability of selecting a red or green marble is 0.6923.

Answer: 12/60 as a percentage is 20%
Step-by-step explanation: boby is 12 and his grandfather is 60 so Bobby’s age is 12/60 of his grandfather and as a percentage it’s 20%
Answer:
To figure out the change, we subtract the original temperature by the following after temperature.
18°F - original
-9°F - subsequent time after original
So we set up the equation;
18°F - (-9°F)
(Two negatives combine to form a positive)
18°F + 9°F
= <u>27°F</u> was the change in temperature.
