Probability.

Question

You are going to draw two candy bars from a large bag containing 26 Snickers bars and 5 Twix bars. What is the probability that the first draw is a Snickers and the second draw from the bag is a Twix? (Assume you are going to keep the candy bars.) Tell whether the two draws are independent or dependent. Calculate the probability.

Answer 1

Snicker: 26/31

Twix: 5/30

Both: (26/31)(5/30), or 130/930.

Events are dependent - first draw affects second choice.
