Interactive practice questions
A spinner is divided equally into $5$5 sections, but $2$2 of them are colored white.
What is the probability of landing on white?
If the spinner is spun $685$685 times, how many times would you expect it to land on white?
$18$18 standard six-sided dice are rolled.
$260$260 standard six-sided dice are rolled.
If Maria rolls a die $48$48 times, how many $2$2s would she expect to come up?
Outcomes
MGSE7.SP.7
Develop a probability model and use it to find probabilities of events. Compare experimental and theoretical probabilities of events. If the probabilities are not close, explain possible sources of the discrepancy.
MGSE7.SP.7a
Develop a uniform probability model by assigning equal probability to all outcomes, and use the model to determine probabilities of events.
MGSE7.SP.7b
Develop a probability model (which may not be uniform) by observing frequencies in data generated from a chance process.
