Key concepts
3 concepts
- 1
If a spinner has seven equally likely possibilities, and four of them are elephants, the probability of spinning an elephant is 4/7.
- 2
If you spin a spinner 210 times, a reasonable prediction for the number of times you'll get an elephant is 120 times, based on the probability of 4/7.
- 3
A prediction based on probability is not a guarantee; it's the most reasonable expectation, but other outcomes are possible.
