Question 1175124
The range is 5 m and one goes from 2-3.5 m or 1.5 m
The probability is 1.5/5 or 0.30.
-
The difference is 3.35 m and the probability is 3.35/5 or 0.67.
-
expected value is midway between the two ends or 4.5 m
-
the variance is (b-a)^2/12 or 25/12.
sd is sqrt of variance or 5/2 sqrt (3) or 5 sqrt(3)/6, or 1.44 m
