For the uniform [5, 10] density below, aka the spinner, what is the probability of the event of getting 8.5 or more? Probability(X28.5) =___________?

Given the following probability distribution for the number of semesters of Math a (non-Math major) college student will take as they earn their degree: x:number of semesters of Math  1 2 3 4 P(x) 0.25 0.45 0.20 0.10   What is the probability that a randomly selected (non-Math major) college student will have taken exactly 3 semesters of Math?   Show how you calculated your result here (type in what you typed on your calculator or computer, etc) Calculation: __________   Now type in your final simplified or rounded answer, if necessary round your answer to four decimal places. P(exactly 3 semesters of Math) = _____________
