7.Develop a probability model and use it to find probabilities of events. Compare probabilities from a model to observed frequencies; if the agreement is not good, explain possible sources of the discrepancy. 9

- a.Develop a uniform probability model by assigning equal probability to all outcomes, and use the model to determine probabilities of events.
*For example, if a student is selected at random from a class, find the probability that Jane will be selected and the probability that a girl will be selected.*4 - b.Develop a probability model (which may not be uniform) by observing frequencies in data generated from a chance process.
*For example, find the approximate probability that a spinning penny will land heads up or that a tossed paper cup will land open-end down. Do the outcomes for the spinning penny appear to be equally likely based on the observed frequencies?*7
