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?

In theory, you should get one 8
for every 7.2 rolls you do.
