Answer
a) .282 b) .303 c) .242 d) .297 e) .0792 f) .738 g) .703
Work Step by Step
a) We use the equation for probability to find: $P=\frac{number\ of\ desired\ outcomes}{total\ number\ of\ outcomes}$ $P = \frac{121+51}{611}=.282$ b) We use the equation for probability to find: $P=\frac{number\ of\ desired\ outcomes}{total\ number\ of\ outcomes}$ $P = \frac{121}{121+279}=.303$ c) We use the equation for probability to find: $P=\frac{number\ of\ desired\ outcomes}{total\ number\ of\ outcomes}$ $P = \frac{51}{160+51}=.242$ d) We use the equation for probability to find: $P=\frac{number\ of\ desired\ outcomes}{total\ number\ of\ outcomes}$ $P = \frac{51}{121+51}=..297$ e) We use the result from part a to find: $P=.282^2=.0792$ f) We use the results above to find: $=\frac{400}{611}+\frac{51}{611}=.738$ g) We use the equation for probability to find: $P=\frac{number\ of\ desired\ outcomes}{total\ number\ of\ outcomes}$ $P = \frac{121}{121+51}=.703$
