Suppose 10% of the flights arriving at an airport arrive early, 60% arrive on time, and 30% arrive late. valerie used the random-number table to find the experimental probability that of 5 flights, at least 2 will arrive late. the digit 0 represents flights arriving early. the digits 1, 2, 3, 4, 5, and 6 represent flights arriving on time. the digits 7, 8, and 9 represent flights arriving late. find the experimental probability that of 5 flights, at least 2 will arrive late. three-tenths two over five nine over twenty eleven over twenty

Michelle and julie work at a catering company. they need to bake 264 cookies for a birthday party that starts in a little over an hour and a half. each tube of cookie dough claims to make 36 cookies, but michelle eats about 1/5 of every tube and julie makes cookies that are 1.5 times as large as the recommended cookie size.it takes about 8 minutes to bake a container of cookies, but since julie's cookies are larger, they take 12 minutes to bake. a. how many tubes should each girl plan to bake? how long does each girl use the oven? b. explain your solution process what did you make? c. what assumptions did you make?
