Answer: Option 'B' is correct.
Step-by-step explanation:
Since we have given that
Number of people who prefer chips = 12
Number of people who prefer pretzels = 14
Total number of people = 50
So, Probability that one preferred the potato chips or pretzels is given by
Probability that one preferred the potato chips or pretzels is
Hence, Option 'B' is correct.

Answer:
P(X ≥ 1) = 0.50
Step-by-step explanation:
Given that:
The word "supercalifragilisticexpialidocious" has 34 letters in which 'i' appears 7 times in the word.
Then; the probability of success = 7/34 = 0.20588
Using Binomial distribution to determine the probability; we have:
where;
x = 0,1,2,...n and 0 < β < 1
and x represents the number of successes.
However; since the letter is drawn thrice; the probability that the letter "i" is drawn at least once can be computed as:
P(X ≥ 1) = 1 - P(X< 1)
P(X ≥ 1) = 1 - P(X =0)
P(X ≥ 1) = 1 - 0.50
P(X ≥ 1) = 0.50
