a) What is the probability that he is accepted to one of the
two schools
this means P( standford or cal-poly)
P( standford or cal-poly) = P( standford) + P(cal-poly) − P(
standford and cal-poly)
= 0.4 + 0.3 – 0.15
= 0.55
What is the probability that he does not get accepted at
either school?
Prob that he gets neither = 1 − 0.55 = 0.45

<span>This would be a bell curve with a z-score of greater than +2.00, since 3 minutes is exactly two standard deviations greater than the mean of 2.00. Looking at a z-score table for the proportion of the curve that lies in the 1-tailed area greater than 2.00, we find that the value is .0228. This would be the probability that the conversation is over three minutes: 0.0228 or 2.28%.</span>
