1) In theory, what is the probability of

spinning orange?

2) If you spin the spinner 20 times, how

many times should you get orange? Prove it

with math! Set up a proportion and solve!!

3) If you did this lab

yesterday, how many times

did your group actually spin

orange out of 20 times?

1) Look on the back brown

chalkboards at our SKUNK

data from all four classes on

Friday. Figure out the fraction

and percent of the rolls all day

that one die had a “1”.

Yesterday we determined that we rolled a “1” about 27% of the time during our game. About how many rolls is that for every “1”?HINT: Think about Unit Rate

Silently study this chart. Think about this

question: How often do you think a sum of 8

happens?

Is it one of the more popular sums (happens

more than other #s) or does it happen

infrequently (not very often)?

1) How many outcomes are there?

2) How many outcomes involve

rolling a sum of 8?

3) In theory, what is the probability

of rolling a sum of 8?
