Question 1177088: Consider an experiment in which each of three cars exiting from a university main entrance turns right (R) or left (L). Assume that a car will turn right or left with equal probability
of 1/2.
(a) What is the sample space S?
(b) What is the probability that at least one car will turn left?
(c) What is the probability that at most one car will turn left?
(d) What is the probability that exactly two cars will turn left?
(e) What is the probability that all three cars will turn in the same direction?

This problem is an exact analog of the well known problem on tossing fair coin.

Instead of events H (head) and T (tail), you have here the events L (left) and R (right).

The rest is the same.
