< 1 >  A church has 9 bells in its bell tower.  

           Before each church service, 5 bells are rung in sequence.

           No bell is run more than once.

           How many sequences are there ??

< 1 > You are planning a trip in an old 2-engine plane.

Probability of either engine failing is 0.10.

>>  what is the probability of both engines failing ??

>>  what is the probability of either engine (only one engine) failing ??

>>   what is the probability of neither engine failing ??

>>  Make sure show all logic and work.

< 2 > Then – create a similar problem and solution of your own from similar data.
