Mini-Project
(Use with Algebra 2, Lesson 12-8)
In groups, complete the laboratory activity below.
Materials:
5 coins, 2 dice, deck of 52 cards, “bag” of 6 red chips, 2 white chips,
and 1 blue chip for each group.
Make predictions using probability for the outcomes of the
situations below. Then actually simulate the situation through
experimentation, filling in the chart. Compare both your results
and the class average to your prediction.

Example
How often will only
3 heads show when
5 coins are tossed
together 16 times? 10 7 9 3 1
1. How often will the
sum of 2 dice be 7
when they are tossed
together 18 times?
2. One card is selected
from a deck of 52. If
13 cards are drawn
how often will the card
be a red card or an 8?
3. Write a conclusion for each experiment based on your own results, the
class average, and the predicted probability.
