# MATH

• WELCOME TO MATH!

We can take the information we learn from probability experiments, and graph it :)

At the top of page 246 you see a tally chart of how many times Tori flipped a coin and landed on 'heads,' and how many times she landed on 'tails.'
You might think that there was more probability of landing on tails, but the only reason it has one more tally mark is because she flipped the coin an odd number of times (25). Therefore, one of the options had to receive the final odd tally mark.

Take a look at Carlos's experiment on page 246.
►Which sum did Carlos pick most often?
►How do you know?
►Which two sums did Carlos pick the same number of times? How many times?
►Why is '1' not listed in the Sum column?
►How many times did Carlos pick two cards from the box?
►How do you know?

Now we can look at problem number 2 on page 246.
Looking at Carlos's chart, which sums are you less likely to pick sums for than others?
ANSWER: You are less likely to pick numbers with a sum of 2 or 6 than a sum of 3, 4, or 5.
