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
