(f+g)(x) = 8x+2
(f-g)(x) = 4x-6
Step-by-step explanation:
Given
we have to find
<u>a. (f+g)(x)</u>
<u>b. (f-g)(x)</u>
Hence,
(f+g)(x) = 8x+2
(f-g)(x) = 4x-6

Answer:
You are selecting marbles with replacement. The marble selections (trials) are independent and the marble selection follows the binomial distribution.
The probability of selecting a red marble the first time is 1313.
(This is because 4 out of 12 marbles are red and412412 reduces to 1313.
The probability of selecting a red marble the second time is 1313.
The marble selections are independent and you can multiply the two probabilities to get the following:
probability of getting 2 reds = (13)2(13)2
=19=19.
So the probability of getting two reds is 1919.
