Question

Question 1
Write your answer in percent form: %
A) You toss a coin 50 times and get 14 tails. What is the
experimental probability of getting heads? (1 point)

Question 2
Write your answer as a decimal:
A) A quality controller inspected 1,000 units of a product
and rejected 120 units due to defects. What is the
probability that a unit WILL pass inspection? (1 point)

Question 3
A) In which scenario is the experimental probability equal to the
theoretical probability? (1 point)
A coin is flipped six times and heads appears five times.
A coin is flipped six times and heads appears three times.
A coin is flipped six times and heads appears each time.
A coin is flipped six times and heads appears one time.

Question 4

A)
A color wheel with six equal sections (blue, red, green,
yellow, black, and white) was spun 150 times. The results
were recorded in this table.

What is the experimental probability of landing on green?
Write your answer as a decimal:
(1 point)

Question 5
Write your answer as a fraction in simplest form:
A) On a Math Test, Gary missed 25 out of 55 questions.
What is the relative frequency of his incorrect
responses? (1 point)

Question 6
people
A) As part of a promotion, people who participate in a
survey are sent a free coupon for one of three winter
activities: skiing, snow boarding, or sleigh rides.
Participants have an equal chance of receiving each
type of coupon. If 600 people participate, how many
people would be expected to receive a coupon for
skiing? (1 point)

Answer 1

Question 1
A) Heads = 50 − 14 = 36. Experimental probability = 36/50 = 0.72 = 72%.

Question 2
A) Passes = 1000 − 120 = 880. Probability pass = 880/1000 = 0.88.

Question 3
A) Theoretical probability for heads = 1/2. Experimental equals theoretical when heads appear 3 times out of 6. Answer: "A coin is flipped six times and heads appears three times."

Question 4
A) The table with the spin results is missing. Please tell me how many times green occurred in the 150 spins.
(If you meant the theoretical expectation instead: 1/6 of 150 = 25, so the probability would be 25/150 = 1/6 ≈ 0.1667.)

Question 5
A) Relative frequency of incorrect responses = 25/55 = 5/11.

Question 6
A) 1/3 of 600 = 200 people.
