Mary has cloth in 4 colors (red, blue, green, yellow)and 2 styles (large, small) for the school logo (star). The flag she is making will have 2 different stripes with white in the middle and the logo. What is the probability that her design will have red and blue stripes and the large logo?
number of possible designs
= (4x3)x2 = 24
the red and blue stripes with large logo is one of those
so prob = 1/24
