Total number of way the clown can make a balloon animal = 4 * 5 = 20

Total number of way the clown can make a purple elephant = 1 * 1 = 1

Probability = \(\frac{1}{20}\)

or

Probability of clown picking the purple balloon = \(\frac{1}{5}\)

Probability of clown making an elephant = \(\frac{1}{4}\)

Probability of clown making an purple elephant = \(\frac{1}{5} * \frac{1}{4}\) = \(\frac{1}{20}\)

Hence option B

An easy probability question..
total ways = 4*5=20
ways to pick purple elephant = 1
so \(P = \frac{1}{20}\)

B

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.

Answer: B
