- Please solve the following Probability and Statistics problem (please double check solution and provide explanation): A binary communication channel carries data as one of two types of signals denoted by 0 and 1. Owing tonoise, a transmitted 0 is sometimes received as a 1 and a transmitted 1 is sometimes received as a 0. For agiven channel, assume a probability of 0.94 that a transmitted 0 is correctly received as a 0 and a probability0.91 that a transmitted 1 is received as a 1. Further assume a probability of 0.45 of transmitting a 0. If asignal is sent, determine 1. Probability that a 1 is received2. Probability that a 0 is received3.

- Q7. A business office orders paper supplies from one of three vendors, V₁, V2, or V3. Orders are to be placed on two successive days, one order per day. Thus, (V2, V3) might denote that vendor V2 gets the order on the first day and vendor V3 gets the order on the second day. (a) List the sample points in this experiment of ordering paper on two successive days. (b) Assume the vendors are selected at random each day and assign a probability to each sample point. (c) Let A denote the event that the same vendor gets both orders and B the event that V2 gets at least one order.
