Answer: The system will succeed when the first alarm rings or when the first one fails, but the second one rings. The probability of this is 0.98
The probability of system failure is 1-(probability of success)= 1-0.98= 0.02
Step-by-step explanation:
There are fifty two weeks in the year.
To find how much commission she earns in a year, multiply her weekly commission by the number of weeks per year.
274*52= 14248
To find how much money is taken from taxes, multiply the amount of money she is taxed weekly by the number of weeks in a year.
68*52= 3536
Now, simply add the amount of money she made in the year with her bonus (which I'm assuming is a one time bonus for being hired) and subtract the amount of money she is taxed.
14248+550-3536= 11262
Mrs. Sanchez earns $11262 a year.
