6.16 independent and dependent events (probability) Graph as a %, fraction, decimal on number line
IXL BB7
Probability is between (0 – 1) 0 no chance 1 always
The closer it is to (1) the stronger the chance.
Graph the probability on a number line. Probability can be represented as a percent, decimal, or a
fraction.
Independent (Replacement)
first roll of a number cube does not influence the second roll of the number cube.
flipping two coins; spinning a spinner and rolling a number cube
flipping a coin and selecting a card
choosing a card from a deck, replacing the card and selecting again.
Ex: When rolling three number cubes simultaneously, what is the probability of rolling a 3 on one
cube, a 4 on one cube, and a 5 on the third?

choosing two marbles from a bag but not replacing the first after selecting it
picking a sock out of a drawer and then picking a second sock without replacing the first
picking a card not replacing then picking a second card
Ex: You have a bag holding a blue ball, a red ball, and a yellow ball. What is the probability of picking
a blue ball out of the bag on the first pick then without replacing the blue ball in the bag, picking a
red ball on the second pick?

without replacing it you pick another. What is the probability of picking 2 cards with girls’ names?
2.
A box of candy has 7 red pieces, 3 orange, 2 yellow, and 8 blue pieces. You get to pick two pieces
of candy. If you reach into the box without looking, what is the probability that you will pick a blue
piece and then a red piece of candy?
3.
A box contains 4 chocolate chip muffins, 2 blueberry muffins, and 1 corn muffin.

corn muffin is chosen?
4.
Mrs. Martin must select two different students to represent the class on the school float in the
parade. She puts the name of each student on a slip of paper and places them into a bag. What is
the probability that she will pick two girls’ names if there are 11 girls and 12 boys in the class?
5.
A bowl holds 4 pieces of green candy and 6 pieces of red candy. You take 1 piece of candy from the
bowl and then a second without replacing the first piece. Assuming a red candy was selected first,
what is the probability that both candies will be red?
6.
A bag has 6 red marbles and 4 blue marbles in it. You pick one, and without replacing it you pick
another. What is the probability of picking 2 blue marbles?

6.18 one-step linear equations in one variable involving whole number coefficients and positive rational
solutions. (fill in blank)
IXL: P5
expression contains a variable (does not have and =)
term is a number, variable, product, or quotient in an expression of sums and/or differences.
In 7x2 + 5x – 3, there are three terms
coefficient numerical factor in a term. 3xy2, 3 is the coefficient;
term z, 1 is the coefficient.
equation is a mathematical sentence stating that two expressions are equal.
variable is a symbol (placeholder) used to represent an unspecified member of a set.
1. If 8 n = 96, what value of n makes the equation true?
2. The classroom teacher wrote the equation shown below for his students to solve to
find the number of kickballs, k, they could buy with the $144, if each kickball cost $9.
144/k= 9
What is the value of k in the equation?
3. Donnie is autographing baseball items. He has a total of 320 baseball cards to sign. He has
signed 14 cards so far. The equation below can be used to determine the number of baseball
cards, c, Donnie still needs to sign.
14 + c = 320
What is the number of baseball cards Donnie still needs to sign?
4. What is the value of n in the equation below?
66 + n = 226
5. At a bakery, there are 16 packages of hamburger buns for sale. The baker placed
8 hamburger buns in each package. He uses the equation below to calculate the
total number of hamburger buns, b, for sale.
b/8= 16
What is the total number of hamburger buns for sale at the bakery?
