Step-by-step explanation:
Let's look at the following exponent rule below:
We can apply this rule to the problem given to help us find the final answer by taking each exponent and <em>subtracting them</em>. Let's illustrate this below:
Hopefully this was helpful! Let me know if you have any more questions.
A) The event is "tossing a number cube once"
The sample space of this event is {1,2,3,4,5,6}.
The expected value of this event is
Since 3.5 is not in the sample space of the event. Therefore, option (A) is not correct.
(B) The event is "Flipping a coin"
Sample space of this event is {HH,TT,HT,TH}
Since sample space of this event is not numbers, therefore, this cannot be the correct option either.
(C) The event is, "Randomly picking a number between 1 and 9, inclusive."
The sample space of this event is {1,2,3,4,5,6,7,8,9}.
Expected value of this event is
Since 5 is the expected value and it is present in the sample space for this event. Therefore, option (C) is a correct choice.
(D) The sample is "Randomly picking a number between one and ten, inclusive".
The sample space of this event is {1,2,3,4,5,6,7,8,9,10}.
Therefore, expected value of the event is
Since 5.5 is not present in the sample space of this event. Therefore, option (D) is not correct either.
Hence, the correct choice is option (C).
