In this situation the calculation o f probabilities o f particular events is sim plified. If the sample space S contains k simple events, then using a uniform probability model we assign probability 1/k to each point in S. To determine the probability o f an event E we need

1. the number o f possible outcomes in S, 2. the number o f outcomes corresponding to E.
