Answer:
The answer is option (A).
Step-by-step explanation:
Let X represent the count of orange milk chocolate M&M’s.
The proportion of orange milk chocolate M&M’s is defined as p = 0.20.
In a small bag containing milk chocolate M&M’s, n is established at 55.The occurrence of an orange milk chocolate M&M is independent of the remaining candies.The random variable X conforms to a Binomial distribution characterized by parameters n = 55 and p = 0.20.
Calculating the average number of orange milk chocolate M&M’s in a package of 55 candies proceeds as follows:
It is noted that in a randomly selected pack of milk chocolate M&M's there were 14 orange M&M's, indicating that the ratio of orange milk chocolate M&M's in that selection was 25.5%.
This ratio is not unexpected.
This is due to the expected count of orange milk chocolate M&M’s in a 55 candy bag being estimated at 11. Therefore, encountering 14 orange milk chocolate M&M’s does not seem unusual.
Unusual instances typically have exceedingly low probabilities, specifically below 0.05.
To calculate the probability of having P (X ≥ 14), follow the subsequent calculation:
The likelihood of obtaining 14 or more orange candies in a milk chocolate M&M’s bag is 0.1968.
This probability is considerably higher than 0.05.
Thus, the correct answer is option (A).
