A credit card company monitors cardholder transaction habits to detect any unusual activity. Suppose that the dollar value of unusual activity for a customer in a month follows a normal distribution with mean $250 and variance $391. What is the probability of $300 to $400 in unusual activity in a month?

b).  Now assume that the transistors of the CMOS logic circuit defined in Fig. 2a (and Question 3a) are sized such that all transistors are the minimum transistor size, which means all the PMOS transistors have a (W/L)p = 1 and all the NMOS transistors have a (W/L)n = 1. For this sizing case, what is the propagation delay for high-to-low output transition (tPHL) at node Y in the worst case? CL = 1pF tPHL =
