1. If a car must have at least 2 passengers in order to be in the carpool lane on this highway, what is the probability that a r

andomly selected car is allowed to be in the carpool lane?
P(x>2) .15+.10+ .3+ .2= .30

2. Find the probability that a randomly  selected car on this highway has fewer than 4 occupants.

P(x<4)= p(x<3)=
.70+ .15+ .10= .95


3. Calculate the mean of this probability distribution.  Click on the tool "Insert Math Equation" in the toolbar above to write your answers using correct notation and round it to one more decimal than is contained in the data (type out your calculations).

E(x) is

1(x) p(1) + 2p(2) + 3p(3)+ 4p(4)+ 5p(5)
.70+.30+.30+.12+.10
=1-52



4. Explain what your answer to #3 means in the context of this problem.

Mean is the expected value and measure of tendency following is the probability of distribution

5. What shape would the probability histogram of this probability distribution have (you do not have to actually create or embed the histogram)?  Explain the meaning of this in context.  In other words, what does this tell you about the driving habits of most drivers on this highway?

Most drivers have more than 2 passengers while driving in the carpool lane on the freeway​
