Question
A jar has 13 candies where six of the candies are red, and seven candies are green. Imagine in a first draw, eight candies are randomly picked from the jar. We are interested in the number of green candies in that first draw. How many green candies do we expect to be in that first draw?Question 1Answera.2b.7c.4.31
Solution
The expected number of green candies can be calculated using the concept of probability.
Step 1: Calculate the total number of candies, which is 13 (6 red + 7 green).
Step 2: Calculate the probability of drawing a green candy. This is the number of green candies divided by the total number of candies, which is 7/13.
Step 3: Multiply this probability by the number of candies drawn (8) to find the expected number of green candies.
So, (7/13) * 8 = 4.31
Therefore, we expect approximately 4.31 green candies to be drawn in the first draw. So, the answer is c. 4.31.
