Document Summary
When flipping two coins the following results are observed: hh, ht, th, tt: define event by describing outcome of each coin; # of heads or tails. : function or rule that assigns number to each outcome of experiment; # of heads. Label random variable x ; for coin toss value of x = 0,1,2. : can take on countable number of values: if x = # of heads observed when flipping con 10 times, values of x are 0,1,2,3 . ,10. : values are uncountable; amount of time to compete a task. Probability distribution probability associated with these values. : table, formula or graph describing values of random variable and. P(x) is equal to and greater than 0 and equal to and less than 1 for all values of x. Sum of all probability of event x is one. Random variable can assume values of x and p(x) is probability that random variable is equal to x .
