Consider an urn with 3 red balls, 2 blue balls, and 1 white ball. You randomly draw 2 balls sequentially from the urn without replacement. Every ball has the equal chance to be selected in each draw. Assume that order matters. Treat the balls identical if they have the same color. "R" denotes the outcome of red ball. "B" denotes blue ball. "W" denotes white ball. a. The sample space S for this experiment is { b. Consider the event A = "none of the drawn balls is red". The list of all the sample points contained in the event A is {_ c. Let X be the random variable counting the number of red balls in the experiment, then X is following a distribution. d. Let B be the event B = "at least 1 red ball is drawn". P(B) = result up to 2 decimal points. Save the final
