A. 1/24 B. 1/20 C. 2/15 D. 3/20 E. 1/8 OA B As with many probability questions, we can solve this by using counting techniques or rules of probability. Let's use rules of probability P(balloon animal is an elephant) = 1/4 [since there are 4 possible animals and 1 is an elephant] P(balloon animal is purple) = 1/5 [since there are 5 possible colors and 1 is purple] P(clown makes a purple elephant balloon animal) = P(balloon animal is elephant AND balloon animal is purple) = P(balloon animal is elephant) x P(balloon animal is purple) = 1/4 x 1/5 = 1/20 Answer: B Cheers, Brent

We can solve this problem as follows,

The probability of clown picking the purple balloon = 1/5

The probability of clown making an elephant = 1/4

The probability of clown making a purple elephant = 1/5 * 1/4 = 1/20

A. 1/24 B. 1/20 C. 2/15 D. 3/20 E. 1/8 The total number of different colored balloon animals can be made is 4 x 5 = 20. Thus, the probability that the clown will make a purple elephant is 1/20.
