Question 1210442
<pre>
Data were collected from a survey given to graduating college seniors on the
number of times they had changed majors. From that data, a probability
distribution was constructed. Use the table below to answer the following
questions, you may round your answers to three decimal places, if necessary.
---------------------------------------------
a. What is the probability that a randomly selected student changed their major
   at least once?

{{{P("">=1) = 1-P(0) = 1-0.234 = 0.766}}}
---------------------------------------------
b. What is the probability that a randomly selected student changed their major
   at most twice?

P(0)+P(1)+P(2) =  YOU ADD THEM UP!
----------------------------------------------
c. What is the probability that they changed majors more than three times?

P(4)+P(5)+P(6)+P(7)+P(8) = YOU ADD THEM UP!
