Answer:

The probability of selecting a martian at random that has not completed 4 or more years is 0.74

Step-by-step explanation:

Hello!

You have the information about the level of studies reached by 171 martians aged 25 and over. (see table in attachment)

Using that information you have to calculate the probability of selecting a martian at random and has not completed 4 or more years, this means that the selected martian could have studied "less than 4 years of high school" or "only 4 years of high school" or "less than 4 years of college"

Be "A" the event "the martian has studied 4 or more years of college"

Its probability is calculated as: P(4.or.more.years)= \frac{total"4 or more"}{n} = \frac{44}{171} = 0.257= 0.26

The complement of A will be A^c  and it's probability is calculated as:

P(A^c)= 1 - P(A)= 1 - 0.26= 0.74

The probability of selecting a martian at random that has not completed 4 or more years is 0.74

I hope this helps!

The initial value of 100 that doubles over each interval.
without the answer choices, I can only describe it and give you an example of the graph. 
I'm assuming the function is 100*(2)^x because if it is as listed it would be a quadratic function with a vertical stretch of 100.
