Question
(Use computer) Suppose 35% of recent college graduates plan on pursuing a graduate degree. Nineteen recent college graduates are randomly selected.
What is the probability that no more than three of the college graduates plan to pursue a graduate degree? (Round your final answer to 4 decimal places.)
What is the probability that exactly eight of the college graduates plan to pursue a graduate degree? (Round your final answer to 4 decimal places.)
What is the probability that at least six but no more than ten of the college graduates plan to pursue a graduate degree? (Round your final answer to 4 decimal places.)

Explanation / Answer
Let x be the number of the recent graduates who plan on pursuing a graduate degree
A) .P(X 4) = 0.203;Excel command: BINOM.DIST(4, 15, 0.40, 1)
B) .P(X= 6) = 0.151;Excel command: BINOM.DIST(7, 15, 0.40, 0)
C) .P(6 X 9) =P(X 9) P(X 5) = 0.9162 0.402 = 0.5142 Excel commands: BINOM.DIST(9, 15, 0.40, 1) and BINOM DIST (5 15 0 40 1 )
