A candy company claims that in a large bag (over 1,000 pieces) of holiday candy half the candies are red and half the candies are green. You pick candies at random from a bag and discover that of the first 50 you eat, 18 are red. a) If it were true that half are red and half are green, what is the probability you would have found that at most 18 out of 50 were red? b) Do you think that half of the candies in the bag are really red? Explain.

Step 1
5 for half red candies), and C(n, x) is the number of combinations of n items taken x at a time. We want to find P(X ≤ 18), which means we need to sum the probabilities for x = 0, 1, 2, ..., 18. Show more…

The following table shows the number of candies of each color in a bag of M&M’s®. $$\begin{array}{|l|l|} \hline \text { Green } & 42 \\ \hline \text { Red } & 28 \\ \hline \text { Brown } & 30 \\ \hline \text { Blue } & 25 \\ \hline \end{array}$$ a. What is the probability that a candy chosen at random will be blue? b. What is the probability that a candy chosen at random will be red? c. What is the probability that a candy chosen at random will be green or brown? d. What is the probability that a candy chosen at random will be a color other than red?
