Its a and b because it simply doesn't make any sense <span />
Six friend =6
A bag popcorn = 9
Share equally 9/6 = 1.5 bag for each person
<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>
