Cerrena [4.2K]

Answer:

The answer is "\bold{\frac{2}{3}}".

Step-by-step explanation:

Pick a shirt first: 3 choices

Pick slacks next: 2 choices

Then choose a tie: 1 choice

Total: 3 \times 2 \times 1 = 6 outfits.

These will be similarly divided between the two slacks, so 3 black slack outfits of 6 = \frac{1}{2}.  Similarly, the 6 styles are also divided between the option of 3 shirts. 2 blue shirt outfits 6 = \frac{1}{3}

To recognize that over outfits are a mix of a blue shirt and black slack, it would be twice many more to add \frac{1}{2} \ and \ \frac{1}{3}. Add \frac{1}{2} \ and \ \frac{1}{3}, and remove the chance for both the black slack shirt and outfit and are one of the six outfits:

\to \frac{1}{2} + \frac{1}{3} -\frac{1}{6} =\frac{3+2-1}{6}  =\frac{4}{6} = \frac{2}{3}
