This is practice for the retake of your check-in on dependent and independent events.

1. Directions: If you would like to retake this Check-
In, you must complete all the problems on the
slides on a separate sheet of paper and turn them
into me. The retakes will be offered next Monday
and Tuesday: before or after school.

2. 1) P(<7)
2) P(4, 6)
3) P(10)
4) P(>3)
5) P(7,8)

3. 6) Make a probability line on your paper.
7) Include the correct likelihood vocabulary.
Write them under your line.
8) Include the decimals under your line.
9) Include the fractions under your line.
10) Include the percents under your line.

4. Determine the following probabilities and then
place the number for each on the line which
you drew on your paper. Use a different
color to place them on your line. Give your
answers as percents.
11) P (red)
12) P (yellow)
13) P (blue)
14) P (red,then green)
15) P (orange)
16) P ( red, yellow, blue, or green)

5. 17) A card is chosen at random from a deck
of 52 playing cards. Without replacing it, a
second card is drawn. What is the
probability that the first card chosen is a
queen and the second card is an Ace? Give
your answer as a fraction.

6. 18) In a shipment of 20 computers, 3 are
defective. 3 computers are randomly
selected and tested. What is the probability
that all 3 are defective if the first two are not
replaced after being tested? Give your
answer as a fraction.

7. 19) A box contains 3 white crayons and 4
black crayons. What is the probability of
drawing 2 black and 1 white crayon without
replacement? Give your answer as a
fraction.

8. Cards that are numbered 1-9 are placed in a
bag. 1 card is pulled out, replaced and then
a 2nd card is pulled out. Find the following
probabilities: (give your answers as
fractions.
20) P (2,5)
21) P (odd, even)
