Binomial Distribution:
- A discrete probability distribution that describes the number of successes in a fixed number of independent trials.
- The distribution has two parameters: n (number of trials) and p (probability of success in each trial).
Variance of Binomial Distribution:
- The variance of a binomial distribution is given by the formula: Var(X) = np(1-p)
- Where X is the random variable that represents the number of successes in n trials.
Given:
- n = 4
- p = 1/3
Calculating Variance:
- Var(X) = np(1-p)
- Var(X) = 4*(1/3)*(2/3)
- Var(X) = 8/9
Answer:
- Therefore, the correct answer is option B, which is 8/9.
