Answer:
D, the observed frequency of landing heads up gets closer to the expected frequency based on the probability of the coin landing heads up.
Step-by-step explanation:
As of now, the observed frequency states that the coin will land on heads 4/12 times. The expected frequency states that the coin will land on heads 50% of the time, or 6/12 times. As the number of trials increases, the observed frequency will get closer to the expected frequency.
Answer: 0.3 .
Step-by-step explanation:
The digits in number system = 10 ( 0 to 9)
The total different nine-digit Social security numbers = 
[By Fundamental counting principle]
= 1 billion
Total people in united state = 300 million = 300, 000 ,000
Since each person In US have equal chance to get chosen.
Therefore , if a number is selected randomly , then the probability that it belongs to one of the 300 million people in the United States :-
Hence, the required probability is 0.3 .
Answer: a continuous random variable
Step-by-step explanation:
<u><em>Can you count the distance it traveled?</em></u> You can't, so it couldn't be discrete because you can count discrete variables.
<u><em>Can you measure the distance it traveled? </em></u>You sure can, that makes it a continuous random variable.
<u><em>Do you know the exact distance it's going to travel?</em></u><u> </u>You won't, therefore it's a random variable since you don't know the value beforehand.
