Using the probability concept, it is found that:
- a) P(star) = 3/8 = 0.375 = 37.5%.
- b) P(not diamond) = 7/8 = 0.875 = 87.5%.
- c) P(flower) = 1/4 = 0.25 = 25%.
- d) You would expect to spin a heart 25 times.
------------------------------------------------
- A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
Item a:
- Of the 8 sections, 3 are stars.
Then:
P(star) = 3/8 = 0.375 = 37.5%.
Item b:
- Of the 8 sections, 7 are not diamonds.
Then:
P(not diamond) = 7/8 = 0.875 = 87.5%.
Item c:
- Of the 8 sections, 2 are flowers.
Then:
P(flower) = 1/4 = 0.25 = 25%.
Item d:
- 2 out of the 8 sections are hearts, then:
Out of 100:
You would expect to spin a heart 25 times.
