Question

Predict the output from the following commands:

Solution

The correct answer is A. 4, 6.

Here's the step-by-step explanation:

  1. The first command X <- c(1, 2) creates a vector X with the elements 1 and 2.
  2. The second command Y <- c(3, 4) creates a vector Y with the elements 3 and 4.
  3. The third command X + Y adds the corresponding elements of X and Y together.

So, 1 (from X) + 3 (from Y) equals 4 and 2 (from X) + 4 (from Y) equals 6. Hence, the output is 4, 6.
