Mark is going to an awards dinner and wants to dress appropriately. He is running behind schedule and asks his little brother to

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:

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