Question

M&M’s The candy company claims that 10% of the M&M’s it produces are green. Suppose the
candies are packed at random into small bags containing about 25 M&M’s per bag. A class of
elementary students learning about percentages opens several bags, counts the various colors, and
calculates the proportion that are green. Simultaneously, a second class performs the same
investigation but their bags contain about 50 M&M’s per bag.
Which class (large bags or small bags) can use the CLT and why?

I don't understand this can you even use the cental limit theorem for this? and how?
