If a baseball player has a batting average of 0.315, what is the probability that the player will get the following number of hits in the next four times at bat? (A) Exactly 2 hits (B) At least 2 hits If a true-false test with 10 questions is given, what is the probability of scoring (A) Exactly 80% just by guessing? (B) 80% or better by just guessing? A coin is loaded so that the probability of a head occurring on a single toss is two thirds. In four tosses of the coin, what is the probability of getting all heads or all tails? The probability of all heads or all tails is nothing (Round to three decimal places as needed.)
