A. The probability Kayla will score above 80% on a mathematics test is 0.60. Kayla will take four tests this semester. We want to find the probability she will score above 80% on exactly three out of the four tests. What is the probability of Kayla scoring above 80% on exactly three out of the four tests? B.
