Answer:
A.
Step-by-step explanation:
We are given the functions f(x) and g(x) as,
It is required to find the function ( f+g ) i.e. ( f+g ) (x)
So,
i.e.
Hence, we get that .
So, the first option is correct.

Step-by-step explanation:
Theoretical probability is what we expect to happen and experimental probability is what actually happens.
a. In theoretical probability, it doesn't matter what happened in the past. So basically we want to know the probability of rolling a 3 when a number cube is rolled.
There are 6 faces (from 1 to 6) in a number cube. And there is 1 "3". So the probabilty of rolling a 3 is:
1/6
b. In experimental probability, we need to know what happened before. When the cube was rolled 450 times, it came up "3", 67 times.
Hence the experimental probabilty of rolling a "3" is:
67/450
