Out of 300 spins, how many times is the pointer of the spinner
expected to land on Win?
Win
Win
Step 1 Find the possible
outcomes of one spin.
There are 8 equal-sized
sections, so there are 8
possible outcomes.
Step 2 Find the theoretical
probability that the pointer will
land on Win.
PWin)
number of Win sections
total number of sections
200
Step 3 Use proportional
reasoning to predict
the likely number of
winning spins, w.
1-300
-300-300-300
75=w
Out of 300 spins, you can expect the pointer to land on Win about 75 times.
On how many out of 200 spins do you expect the pointer to land on Win?
1. How many equal-sized sections does this spinner have?
2. Find the theoretical probability that the pointer will land on Win.
P(Win) number of Win sections
total number of sections
-8-6
3. Complete the proportion to find the number of expected wins,
w, in 200 spins.

4. On how many out of 200 spins do you expect the pointer to land on Win?
