Algebra and Probability Review

What is the probability of rolling a 6 with one die and landing a coin on heads? Show a tree diagram to explain your answer.

Solving one step algebra equations

Apply the opposite operation

The 3 steps for solving one step algebra equations:

1st- Isolate the variable

2nd- Apply opposite operation

3rd- Check your work

Sorry for the big gap in the end, something went wrong when I put my pictures in.

Probability

There's 4 coins in a cup- 0.25, 0.10, 0.05, 0.01
You draw 1 coin then put it back, then draw another coin. If those 2 coins add up to an even sum you win. If they add up to and odd sum you lose.
Do you want to play? Explain the odds, are they in your favor or not.

Organize Outcomes
Create a Table or a Chart

P (even sum)=10/16 or 5/8 or 62.5%
P (odd sum)=6/16 or 3/8 or 37.5%


A coin is flipped and a six sided die is rolled.These 2 are called independent events.
Independent event- The outcome of one event has no effect on the outcome of another event.
Sample Space- All possible outcomes of an experiment.

A coin is flipped and a six sided die is rolled
a)Use a table to list all possible outcomes.
b)How many possible outcomes are there
c)Write the sample space for this combination of events.

Possible outcomes:12
Sample space: (H1) (H2) (H3) (H4) (H5) (H6)
(T1) (T2) (T3) (T4) (T5) (T6)
Find P (heads and even)
3/12=1/4 or 25% or 1:4
