7. Disagree.
8. If the events are independent, the probability of both/all events occurring is determined by multiplying the probabilities of the individual events.
4/10 * 2/10 = ?
9. Correct
10. P(heads) = 1/2
P(<5) = P(4 or 3 or 2 or 1)
Either-or probabilities are found by adding the individual probabilities.
1/2 * 4/6 = 4/12 = ?
7. Which of the following is an example of independent events?
A rolling two number cubes
B selecting marbles from a bag without
replacement after each draw
C choosing and eating a piece of candy from a dish and then choosing another piece of candy***
D Pulling a card from a deck when other players have already pulled several cards from that deck
8. A bag of fruit contains 4 apples, 1 plum, 2 apricots, and 3 oranges. Pieces of fruit are drawn twice with replacement. What is P(apple, then
apricot)? (1 point)
a 4/5
b 2/25
c 3/25***
d 3/5
9. A coin is flipped three times. How the does P(H, H, H) compare to P(H, T, H)? (1 point)
A. P(H, H, H) is greater than P(H, T, H)
B.P(H, T, H) is greater than P(H, H, H).
c.The probabilities are the same.***
d.There is no way to tell with the information given.
10. A coin is tossed and a number cube is rolled. What is P(heads, a number less than 5)? (1 point)
A 1/3***
B 5/12
C 2/3***
D 5/6
