Subtracting 90° from the argument of the sine function shifts its graph 90° to the right, putting the negative peak on the y-axis. That corresponds to the negative cosine function, choice D.

Experimental probability is the result of an experiment. Theoretical probability is what is expected to happen.

Oxana [17]

Answer:

See Explanation

Step-by-step explanation:

<em>The question is incomplete, and it can be interpreted in different ways.</em>

Is the question a true or false question?

If yes, then both statements are true

As a further explanation, we consider a roll of die.

The sample space is:

$S = \{1,2,3,4,5,6\}$

Because 1 to 6 appear just once on the die, then each have a probability of 1/6

$Pr = \frac{1}{6}$ --- This is referred to as the theoretical probability

But if after rolling the die 6 times, the outcome is:

$Outcome = \{1,1,4,5,1,2\}$

The experimental probability of (say 1) is, the number of times 1 appeared divided by the number of times the experiment is carried out.

i.e.

$Pr(1) = \frac{3}{6}$
