Probability of Drawing Tokens

Very Hard Data Analysis And Probability Probability

A container holds 12 distinct tokens: 4 red, 5 blue, and 3 green. If 4 tokens are drawn at random from this container without replacement, what is the probability that at least 2 tokens drawn are blue?

To compute the probability, consider using complementary counting by first calculating the chances of drawing fewer than 2 blue tokens.

$$ \frac{11}{22} $$

$$ \frac{23}{66} $$

$$ \frac{31}{66} $$

$$ \frac{17}{66} $$
