Determine the probability of all four engines during flight

Assignment Help Basic Statistics
Reference no: EM13954287

Suppose you are flying a four-engine aircraft on a 10-hour transoceanic flight. Assume that it has been established that the probability of an engine of the type you have on your aircraft failing during a 10-hour flight is 0.008. Determine the probability of all four engines failing during the flight.

A student decided that this is a binomial distribution problem. Remember that the four characteristics of a binomial distribution are:

Fixed number of trials

Two possible outcomes

Fixed probability of success

Independence of events

Evaluate the problem in terms of the four characteristics and explain whether you think it does or does not fit the characteristics of a binomial distribution. If not, which characteristics do not hold? Note that in determining whether or not a problem is binomial or not, you must evaluate it against the four characteristics listed above.

The student found that the probability of all four engines failing is 4.1E-09. Is that answer correct?
