3. Each time a modem transmits one bit, the receiving modem analyzes the signal arrives and decides whether the transmitted bit is 0 or 1. It makes an error with probability p, independent of whether any other bit is received correctly. a) If the transmission continues until first error, what is the distribution of random variable X, the number of bits transmitted? b) If p = 0.1, what is probability that X = 10? c) what is probability that X > 5? d) If modem transmits 30bits, what is the distribution of random variable Y, the number of error? e) If p = 0.15, what is probability that Y< 3, f) if the transmission continues until third error ,what is the distribution of random variable Z, the number of bits transmitted? g) If p = 0.2, what is probability that Z = 5? h) what is probability that Z > 5

Consider 3 time periods (now, a bit later, a lot later). The “Now” period: If a student goes to school now, they will have to pay $100 for books/transportation/fees/etc. In addition, they will not be able to work, hence the family income is reduced by $600. The “a bit later” period: If a person goes to school in the “now” period, they will earn $500 more than a person who does not go to school. The “a lot later” period: If a person goes...
