The waiting time X to get on a certain network can be 1, 5, 10 or 12 seconds. Find P(X = 5), P(X ≥ 2), P(3 < X < 12) if the probability mass function of X is:
x: 1 5 10 12
f(x): .6 .2 .1 .1 (respectively)
Homework Answers
From given information we have
P(X=5) = 0.20
P(X>=2) = P(X=5) + P(X=10)+P(X=12)=0.2+0.1+0.1 = 0.40
P(3<X<12) = P(X=5) + P(X=10) = 0.2+0.1 = 0.30

The waiting time in years for a certain type of fan-belt to fail is known to...
The waiting time in years for a certain type of fan-belt to fail is known to have a distribution function, f(x)= 1/3 e-x/3, with an average waiting time of 3 years. Let the random variable X denote the waiting time to failure of a randomly selected fan-belt. Find the value of ksuch that P(X≤k)=0.6. If we have been waiting at least 5 years, what is the probability the total waiting time will be at least 6 years?

Can you solve 12
Thus, the expected time waiting is 5/6 hours (or 50 minutes) (Note that it is wrong to reason like this: Alice expects to arrive at 12:30, Bob expects to arrive at 1:00: thus, we expeet that Bob will wait 30 mimutes for Alice.) (b). We want to compute the probability that Bob has to wait for Alice, which is P(Y < X), which we do by integrating the joint density, f(r,y), over the region where <...
