18 students are likely to be wearing red

Step-by-step explanation:

From the question, we know a student either wears red, or blue, with the probability of a student wearing red is 3 times more probable than wearing white.

So, let's say out of the 24 students, x of them are wearing white. What this practically mean is that 3 * x = 3x of the students would be expected to be wearing red.

Now, adding the number of people wearing red and white together in terms of x, we have x + 3x = 4x

We equate this to 24; 4x = 24 and x = 24/4; x = 6

The number wearing red probably is 3 * x = 3 * 6 = 18 people
