Describe a probability simulation for each situation

1. You guess the answers on a true/false test with 20 questions
2. One student out of 6 is randomly chosen to be the homeroom representative

Step-by-step explanation:

Situation 1:

You guess the answers on a true/false test with 20 questions

Simulation:

- We could flip 20 coins assigning "Heads" as correct answers and assigning "Tails" as in-correct answers. We see that the simulation and situation both have probability of answering the correct answers or flipping "Heads" to be independent events. The probability of answering the question correctly must be equal to the likely-hood of getting a "head" i.e p = 1/2.

Situation 2:

One student out of 6 is randomly chosen to be the homeroom representative.

Simulation:-

- We could roll a fair die with each number assigned to each each student. The probability of getting any number on die is independent and random. Whatever number the die faces up on a roll select the corresponding assigned student. The probability of selecting a random student out of 6 must be equal to the likely-hood of getting any number on the die i.e p = 1/6.

(d)

step-by-step explanation:

given: the line in the graph passes through points (5,30) and (6,26).

then, the equation of line is:

now, put y=a(n) and x=n,

hence, option d is correct.
