Answer:
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

Step-by-step explanation:




Hence


Hopefully you get what I meant!!
This can be proven by using the Pythagorean theorem. Draw a circle and label the radius 4 cm. Then draw the diameters in to create a perpendicular intersection at the center. If you then label the points that make the diameter, you will see that when connected they create right isosceles triangles. a^2 + b^2 = c ^2, so 4 x 4 + 4 x 4 = c^2. 32 = c^2. Because you are going to be multiplying it by itself to calculate the area, you have you answer of 32 square centimeters. NO need to find the square root and them square it again!
