Question 1191345
In a binomial distribution with n=4 and p=1/2, the median is **2**.

Here's why:

* **Binomial Distribution:** A binomial distribution describes the probability of getting a certain number of successes in a fixed number of independent trials, where each trial has the same probability of success.

* **n = 4:** This means there are 4 trials.
* **p = 1/2:** This means the probability of success on each trial is 1/2 (or 0.5).

* **Median:** The median is the value that divides the distribution in half. Since p = 1/2, the binomial distribution is symmetric.  In a symmetric binomial distribution, the median is equal to the mean.

* **Mean of a Binomial Distribution:** The mean (μ) of a binomial distribution is given by μ = n * p. In this case, μ = 4 * (1/2) = 2.

Since the distribution is symmetric, the median is equal to the mean. Therefore, the median is 2.
