After surveying students in her homeroom, Katie decided to use a number cube to predict the probability that a randomly chosen s
tudent in her school planned to stay after school today for extracurricular activities. In Katie’s simulation, a roll of 1 represents staying after school, while rolls of 2, 3, 4, 5, or 6 represent leaving school at the end of classes. According to Katie’s model, what is the probability that three randomly chosen students will all stay after school for extracurricular activities today?
A.1/729
B.1/216
C.1/18
D.1/8
Step-by-step explanation:First you need to add A and 2A together. that equals 3a. Since 3 is left , it could be -1 and 4 because it would equal the same thing hope this helped :)
