A random variable `X` has the following probability distribution: `X=x_i :\ 1 \ \ 2 \ \ 3 \ \ 4` `P(X=x_i):\ \ k \ \ 2k \ \ 3k \ \ 4k` Write the value of `P(X geq3)` .

Explanation

To solve the problem, we will follow these steps:

### Step 1: Write down the given probability distribution.
The random variable \( X \) has the following values and corresponding probabilities:
- \( X = 1 \) with \( P(X = 1) = k \)
- \( X = 2 \) with \( P(X = 2) = 2k \)
- \( X = 3 \) with \( P(X = 3) = 3k \)
- \( X = 4 \) with \( P(X = 4) = 4k \)
