Probability

Let A, B and C be Boolean variables denoting three independent events with P(A=1) = 0.7, P(B=1) = 0.3, and P(C=1) = 0.1. Let D be the event that at least one of A and B occurs, i.e., D = A OR B. Let E be the event that at least one of B and C occurs, i.e., E = B OR C. Let F be the event that exactly one of A and B occurs, i.e., F = A XOR B.

(a) (4 pts) Express F as a set of clauses (i.e., as a conjunction of disjunctions) involving A and B.

(b) (9 pts) Suppose that A and E are true. What is the probability that B is true? Show your work.

(c) (9 pts) Suppose that D and E are true. What is the probability that A is true? Show your work.

Write a program that inputs the values of three Boolean variables, a, b, and c, from a “cin” operator (user gives the values be sure to prompt user for what they have to give!). Then the program determines the value of the conditions that follow as true or false. 1. !(a&&b&&c) && ! (a||b||c) 2. !(a||b)&&c Output should include the values of a,b,c ie 0 or 1 in the patterns that follow reflecting the Boolean logic being tested. Where “True”...
