Probability is the study of determining the chances of an event being successful or not. To determine the probability of, say, 5 events happening, you would have to add their individual probabilities. For the probability of household having less than 3 televisions, you add the data for 2, 1 and 0 televisions.
Total Probability = 3% + 11% + 28% = 42% (or 0.42 if in decimal form)
Answer:
B.
Step-by-step explanation:
Since i is in the denominator, if i = 0, then the result will be undefined. Therefore, B cannot be a value of θ.

Answer: Negative</h3>
Reason:
The template 
applies to any quadratic to graph out a parabola. The coefficient for the x^2 term is 'a', and it solely determines whether the parabola opens upward or downward.
If 'a' is negative, then the parabola opens downward. The way to remember this is that 'a' being negative forms a negative frown.
On the other hand if 'a' is positive, then it forms a positive smile, and the parabola opens upward.
In this case, the points are fairly close to a parabola opening downward. This means 'a' is negative and a < 0.
