The probability of each number of planes sold of 0, 1, 2, or 3 of every 50-week deals office can be resolved utilizing the proportion of events of a particular occasion and the aggregate number of results. This tool can be used because information has been gathered before, and the normal is given to us. In light of the past data, the probability of selling 0 planes is as follows:

40/50 (40 divided by 50) = 0.8

The probability of selling one plane is:

8/50 (8 divided by 50) = 0.16

The probability of selling two planes is:

1/50 (1 divided by 50) = 0.02

The probability of selling three planes is:

1/50 (1 divided by 50) = 0.02

**Decide what approach is best used to determine probability. Distinguish between the approaches to make it clear that the approach used was the best fit for these airplane sales.**

The best approach that can be utilized to decide probability is the subjective approach. Through a subjective approach, the probability that a given occasion will happen is dictated by every one of the information that has been provided about the event. In this manner, in the wake of thinking about the data, it at that point winds up conceivable to concoct a given rate that will speak to the odds that an occasion will happen once more (Garvey, Book, & Covert, 2016). For the situation examined, the quantity of planes sold within five years has been provided. Extra information incorporates the period in weeks inside which these planes were sold. Consequently, the data can be dissected to give an example that will expand the probability for the number of planes to be sold in the sixth year and inside the period in which they will have been sold.

Extra ways to deal with probability incorporate a traditional definition. The established definition becomes possibly the most important factor when there are a given number of results that are normal for an occasion. There could be more than one result; however, these outcomes can’t surpass the circumstances (Anderberg, 2014). For instance, there are six likely outcomes when a bite of the dust is rolled. Notwithstanding, just a single result will be gotten at a given time. A moment case is a point at which a coin is flipped. There are only two sides to a coin. In this way, regardless of whether it’s just a single result that will be obtained when the coin is flipped, there is likely a moment probability. Be that as it may, only a single of the two results can be obtained regardless of how often the occasion is rehashed. In conclusion, relative recurrence is the third way to deal with repetition. It alludes to the probability of an incident happening after the circumstances of an occasion with restricted events. The approach also takes into account an opportunity to be attempted and its results noted. At that point, the circumstances for every probability are resolved.

**Determine if the approach would change if we also needed to track sales of some planes with GPS installed.**

The approach would not change when if the planes were to be fitted with GPS. The way that after a plane has been sold implies that regardless of what happens, the plane can’t be exchanged once more. In this way, once sold, that occasion won’t happen again (Garvey et al., 2016). Because of this, the way to deal with decision likelihood won’t change; however, it will turn out to be more precise. The idea that it will be conceivable to distinguish every one of the planes sold is the motivation behind why the procedure will turn out to be significantly more precise. It is subsequently reasoned that there wouldn’t be any adjustments in the likelihood approach even with the progressions made.
