Answer: B. a physical model.
The world has lots of different kinds of models. A mathematical model might be a ball travels according to the equation
. This isn't that. A computer model would be a program that somehow simulates a skeleton in the computer, this isn't that either. Our skeleton is an actual physical model just like a model airplane.
Answer: 0.5
Step-by-step explanation:
Formula for binomial probability :-
, where P(x) is the probability of getting success in x trials , n is the total number of trials and p is the probability of getting success in each trial.
Given : The number of trails : n=7
The probability of success for each trial : p=0.5
Now, the probability that the number x of correct answers is fewer than 4 will be :-

Hence, the probability that the number x of correct answers is fewer than 4 = 0.5
When you divide these you get
15.25/244=0.0625
<h3>C. <u>x > 42 </u></h3>
