To explain: Whether the binomial distribution could be used to approximate the

Answer to Problem 102E
No, it cannot be used.
Explanation of Solution
Given:
Number of tiles being chosen = 7
Number of vowels = 42
Number of consonants = 56
Number of blank tiles = 2
Here, probability of success is not fixed and also the trials are dependent on each other. And, for the binomial distribution the probability of success must be fixed for each trial. Also, the trials must be independent of each other.
Hence, the binomial distribution could not be used to approximate the probability
