Step-by-step explanation:
If we call the number we're looking for n, then
n * 60/100 = 15
then n = 15/0.6 = 25
Answer:
41/3
Step-by-step explanation:
given that your waiting time for a bus in the morning is uniformly distributed on [0, 8], whereas waiting time in the evening is uniformly distributed on [0, 10] independent of morning waiting time.
Sum of both waiting times = X+Y
Where X = morning wait time is U(0.8) and
Y = evening wait time is U(0,10)
Since X and Y are independent
Var(x+y) = Var(x)+Var(y)
Var(x) = 
Var(Y) = 
Var(x+y)
