According to a poll done in 2010, 55% of adults aged 25-29 had only a cell phone (no landline). Assume that two randomly selected adults (aged 25-29) are asked whether they have only a cell phone. Complete parts a through e below. a. If a person has only a cell phone, we will record Y (for Yes). If not, we will record N. List all possible sequences of Y and N for this experiment. O A. Y, N, YY, YN, NY, NN O B. YY, YN, NY, NN O C. YY, YN, NN O D. YY, YY, YN, NY, NN, NN b. For each sequence, find by hand the probability that it will occur, assuming each outcome is independent. Select the correct choice below and fill in the answer boxes to complete your choice. (Type integers or decimals. Do not round.) O A. P(YY) =. P(YN) =. P(NY). P(NN) = O B. P(Y)=. P(N) = OC. P(YY) =.
