Use the Binomial Probability Equation:
An Olympic archer is able to hit the bull’s-eye 80% of the time.
Assume each shot is independent of the others.
If she shoots 6 arrows, what is the value of 'n'?
Use the Binomial Probability Equation:
An Olympic archer is able to hit the bull’s-eye 80% of the time.
Assume each shot is independent of the others.
If she shoots 6 arrows, what is the value of 'p'? (probability of success, hitting the bull's-eye)
Enter your answer as a decimal.
Use the Binomial Probability Equation:
An Olympic archer is able to hit the bull’s-eye 80% of the time.
Assume each shot is independent of the others.
If she shoots 6 arrows, what is the value of '1-p' (also known as q )?
(probability of failure, not hitting the bull's-eye)
Use the Binomial Probability Equation:
An Olympic archer is able to hit the bull’s-eye 80% of the time.
Assume each shot is independent of the others.
Use the formula:
If she shoots 6 arrows, what is the probability that she gets exactly 4 Bull’s-eyes?
P(X=4):
Use the TI-Nspire to find your answer.
Enter your answer as a decimal rounded to three places past the decimal point.
An Olympic archer is able to hit the bull’s-eye 80% of the tme.
Assume each shot is independent of the others.
Use the formula:
If she shoots 6 arrows, what is the probability that she gets exactly 5 Bull’s-eyes?
P(X=5):
Enter your answer as a decimal rounded to three places past the decimal point.
An Olympic archer is able to hit the bull’s-eye 80% of the tme.
Assume each shot is independent of the others.
Use the formula:
If she shoots 6 arrows, what is the probability that she gets all 6 Bull’s-eyes?
P(X=6):
Enter your answer as a decimal rounded to three places past the decimal point.
Using the information from the previous three questions, what is the probability that the Olympic Archer is able to hit the bull's-eye at least four times out of 6 shots?
Hint: P(at least 4 bull’s-eyes)= P(4 bull's-eyes) or P(5 bull's-eyes) or P(6 bull's-eyes)
A basketball player, who has made 70% of his foul shots during the season, gets to take 5 shots in the first playoff game.
Assuming the shots are independent, what's the value of 'n'?
A basketball player, who has made 70% of his foul shots during the season, gets to take 5 shots in the first playoff game.
Assuming the shots are independent, what's the value of 'p'? (probability of success, making the basket)
Enter your answer as a decimal.
A basketball player, who has made 70% of his foul shots during the season, gets to take 5 shots in the first playoff game.
Assuming the shots are independent, what's the value of '1-p' (or q)?
(probability of failure, not making the basket)
Enter your answer as a decimal.
A basketball player, who has made 70% of his foul shots during the season, gets to take 5 shots in the first playoff game.
Now that you have identified n, p, q, use the formula:
Assuming the shots are independent, what's the probability he makes exactly 3 of the 5 shots?
Enter your answer as a decimal rounded to three places.
A basketball player, who has made 70% of his foul shots during the season, gets to take 5 shots in the first playoff game.
Now that you have identified n, p, q, use the formula:
Assuming the shots are independent, what's the probability he makes exactly 4 of the 5 shots?
Enter your answer as a decimal rounded to three places.
A basketball player, who has made 70% of his foul shots during the season, gets to take 5 shots in the first playoff game.
Now that you have identified n, p, q, use the formula:
Assuming the shots are independent, what's the probability he makes all 5 of the 5 shots?
Enter your answer as a decimal rounded to three places.
A basketball player, who has made 70% of his foul shots during the season, gets to take 5 shots in the first playoff game.
Use the answers to the previous three questions: what's the probability he makes at least three of the 5 shots?
Enter your answer as a decimal rounded to three places.
A basketball player, who has made 70% of his foul shots during the season, gets to take 5 shots in the first playoff game.
Use the answers to the previous question: what's the probability he makes less than three of the 5 shots?
Enter your answer as a decimal rounded to three places.
Hint: At least three shots has a complement, what is the opposite of making at least 3?
Use the fact that complements need to add to 1.0 to find your probability for less than three shots.
