Madison Middle School has a math and science club that holds meetings after school. The club has decided to enter a two-day comp
etition that involves different a math science challenges. The first day of competition involves solving multi-step math problems. Teams will receive two points for every problem they get correct in the morning session and three points for every question they get correct in the afternoon session.
a. Write an equation to represent the situation. Remember to define your variable(s)
b. The team scores four points in the morning session, but finishes the day with 28 points. Solve the equation and interpret the solution in the context of the problem.
c. The second day of the competition the science portion, involving hands-on science problems. Each correct science problem is worth 5 points. If the team started the day with 28 points and ended with 53 points, how many science problems did they get correct? Write and solve the an equation to answer the question.

Answer:
0.0467
Step-by-step explanation:
Probabilty of being defective is
So probability of being good is
Now,
Probability that all 3 of them are good is:
Now, to find probability of rejection, we subtract the now found probability from 1. Thus, we have:
1 - 0.9533 = 0.0467
