Answer:
Option A.
<em>The number of elements in the sample space of this experiment is 84</em>
Step-by-step explanation:
The sample space for an experiment represents the number of possible results that may occur when conducting the experiment.
When throwing a die and observe the number obtained there are 6 possible results
When throwing a coin there are 2 possible results.
When spinning a wheel divided into 7 regions we have 7 possible outcomes.
If we combine these three experiments, then the sample space S is composed of the product of the possible results of each experiment.

Answer:
False
Step-by-step explanation:
y = 2x + 1
Substitute the point (4,3) into the equation and see if it is true
3 = 2(4) +1
3 =8+1
3 =9
This is false, so the point is not a solution
The sum of a number.....means addition
ur expression would be : x + 21
