Unformatted text preview: 6 th order statistic is 49 and 7 th order statistic is 60. The total distance is 11 units. We wish to go 40% of that, which is 4.4. The 80 th percentile is 53.4. 2. 1) Two events are independent. Therefore, P(A n B)=P(A)P(B). P(A U B)=P(A)+P(B)P(A n B) = P(A)+P(B)P(A)P(B)=1/5+1/41/20=8/20=2/5 2) Two events are mutually exclusive. Therefore, P(A n B)=0. P(A U B)=P(A)+P(B)P(A n B) = P(A)+P(B)=1/5+1/4=9/20....
