For example, if the probability of Jazmin guessmg t e correct answer on a mulitple choice question is 0.20, then guessing the answer on a multiple-ch01ce question can be modeled by a toss of an unfair coin for which Heads is associated with Correct and Tails with incorrect. Thus, the probability of Jazmin guessing correctly 4 answers on a mutiple choice test With 7 questions is exactly the same as the probability of getting 4 heads from tossing the coin 7 times and can be computed using the following formula HRH) = 05pm p)\" " *' \\Nlth n 2 7, k = 4, andp : 020. P(4H/T) = 047 - 0.201 - 0.83 = 35 0.0010 0512 = 0.0287 Find the probability of Jazmin guessing correctly 2 anSWers on a mutiple choice test with 8 questions: (Round the answer to 4 decimal places.)
