Then, the probability that the number of heads is different rom the number of tails is Question An urn contains 3 blue balls and 2 red balls. They are removed at random and not replaced. The probability that the last ball drawn is red is □ 3/5 □ 2/5 1/5 Question Consider a biased coin where P(Head)-p-1 -q, i.e. it is Bernoulli(p) Then, the probability that an even number of heads accurs after 4 tosses (zero is an even number) is given by
