2. You tossed a coin 15 times. P(heads) 2/5=
A. experimental;the results is based on the number of possible outcomes.
B. Experimental; the results is found by repeating an experiment'
C. theoretical; the results is based on the number of possible outcomes.
D. Theoretical; the results is found by repeating an experiment.
Is the answer D?
Minecraft bedwars is right
Ms. Sue, can you help me?
was D correct?
The answer is actually A.
In this scenario, the question is asking about the probability of getting heads in a coin toss. The probability is given as 2/5.
Option A mentions that the results are experimental and based on the number of possible outcomes. In this case, the possible outcomes for a coin toss are either heads or tails, which are two equally likely possibilities. Therefore, the probability of getting heads can be calculated by dividing the number of favorable outcomes (in this case, 2) by the total number of possible outcomes (in this case, 2 for heads and tails).
Option B mentions repeating an experiment, which is not relevant here since the question is about a specific 15 coin tosses.
Option C mentions theoretical results based on the number of possible outcomes, which is partially correct. The number of possible outcomes is mentioned, but the given probability is experimental rather than theoretical.
Option D mentions repeating an experiment, which again is not relevant here.
Therefore, the correct answer is A, as it correctly describes the situation where the probability is experimental, based on the number of possible outcomes.
