\(\nabla\) Describe an experiment in which two coins are flipped and the set of outcomes is \(\\{0,1,2\\}\).
You wish to ascertain the probability of an event \(E\), but you happen to know that the event \(F\) has occurred. Is the probability you are seeking \(P(E)\) or \(P(E \mid F)\) ? Give the reason for your answer.
You are given a transition matrix \(P\) and initial distribution vector \(v\). Find (a) the two-step transition matrix and (b) the distribution vectors after one, two, and three steps. $$ P=\left[\begin{array}{ccc} .1 & .1 & .8 \\ .5 & 0 & .5 \\ .5 & 0 & .5 \end{array}\right], v=\left[\begin{array}{lll} 0 & 1 & 0 \end{array}\right] $$
Pablo randomly picks three marbles from a bag of eight marbles (four red ones, two green ones, and two yellow ones). How many outcomes are there in the sample space?
Complete the following probability distribution table, and then calculate the stated probabilities. $$ \begin{array}{|r|c|c|c|c|c|} \hline \text { Outcome } & \mathrm{a} & \mathrm{b} & \mathrm{c} & \mathrm{d} & \mathrm{e} \\ \hline \text { Probability } & .1 & .05 & .6 & .05 & \\ \hline \end{array} $$ a. \(P(\\{a, c, e)\\}\) b. \(P(E \cup F),\) where \(E=\\{\mathrm{a}, \mathrm{c}, \mathrm{e}\\}\) and \(F=\\{\mathrm{b}, \mathrm{c}, \mathrm{e}\\}\) c. \(P\left(E^{\prime}\right),\) where \(E\) is as in part (b) d. \(P(E \cap F)\), where \(E\) and \(F\) are as in part (b)
