A man owns five bow ties. He chooses one bow tie at random to wear on any given day. The polka-dot bow tie is his favorite, so his random process uses a larger probability for that bow tie. The rest of the bow ties are given equal probabilities of being chosen, as shown in the table.Polka DotStripesCheckeredArgylePaisley0.40????

Answer
A
0.15
B
0.20
C
0.25
D
0.60

Explanation

The probabilities for all five bow ties must add up to 1. The polka-dot tie has probability 0.40, leaving 1 − 0.40 = 0.60 for the other four ties. Since those four are equally likely, each has probability 0.60 ÷ 4 = 0.15, so the correct choice is 0.15.
