1) There are two more assignments in your course before the semester ends, and if you get an A on at least one of them, you will get an A for the semester. Your "what-if" scenario looks like this: Event Probability A on paper and A on presentation .25 A on paper only .10 A on presentation only .30 Do not get an A on either .35 Answer the following questions: (1 point each, except the last item, 2 points) 1a) What is the probability of getting an A on the paper?

The probability of getting an A on the paper is 0.35.

Step-by-step explanation:

The events of getting an A on the paper and presentation can be defined as follows:

X = Event of getting an A on the paper.

Y = Event of getting an A on the presentation.

The probabilities of these events are:

P (Only X) = 0.10

P (Only Y) = 0.30

P (X ∩ Y) = 0.25

Consider the Venn diagram below.

According to the Venn diagram the probability of getting an A in the paper, i.e. P (X), can be computed as:

                                P (X) = P (Only X) + P (X ∩ Y)

Compute the probability of X as follows:

Thus, the probability of getting an A on the paper is 0.35.

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
