The values of three independent observations of Xare denoted by X,. X, and X,. (b) Given that X, +I +I¸ =9, determine the probability that at least one of these three values is equal to 2. Freda chooses values of X at random until she has obtained X = 2 exactly three times. She then stops. (c) Determine the probability that she chooses exactiy 10 values of X.

Question

Please can you help me with parts b and c?

Thank you so much.

In this question you must show detailed reasoning. The random variable Ihas probability distribution defined as follows. 15 + x=2,3,4,5, P(X=x) = 64 otherwise. (a) Show that P(X=2) = The values of three independent observations of X are denoted by X,. X, and X,. (b) Given that X, +X_ +X¸ = 9. determine the probability that at least one of these three values is equal to 2. Freda chooses values of Xat random until she has obtained X = 2 exactly three times. She then stops. (c) Detemine the probability that she chooses exactly 10 values of X.
