Let X Represent the Number of Computers in Australian Households $$\begin{array} { | l | r | r | r | r | r | } \hline x & 1 & 2 & 3 & 4 & 5 \\\hline p ( x ) & 0.25 & 0.33 & 0.17 & 0.15 & 0.10 \\\hline\end{array}$$

question 33

Short Answer

Let X represent the number of computers in Australian households who own computers. The probability distribution of X is as follows: $$\begin{array} { | l | r | r | r | r | r | } \hline x & 1 & 2 & 3 & 4 & 5 \\\hline p ( x ) & 0.25 & 0.33 & 0.17 & 0.15 & 0.10 \\\hline\end{array}$$ What is the probability that a randomly selected Australian household will have:
a. more than 2 computers?
