Players in sports are said to have "hot streaks" and "cold streaks." For example, a batter in baseball might be considered to be in a slump, orcold streak, if that player has made 10 outs in 10 consecutive at-bats. Suppose that a hitter successfully reaches base 22% of the time he comesto the plate. Complete parts (a) through (d) below......(a) Find the probability that the hitter makes 10 outs in 10 consecutive at-bats, assuming at-bats are independent events. Hint: The hitter makesan out 78% of the time.P(hitter makes 10 consecutive outs) =(Round to five decimal places as needed.)

Given,The probability of a hitter successfully reaches baseis 0.22The probability of the hitter…
