You're at a clothing store that dyes your clothes while you wait. You get to pick from 4 pieces of clothing
Zielflug [23.3K]

1 / 12 is the probability that you'll end up with an  orange hat.

<u>Step-by-step explanation:</u>

Given that,

  • There are 4 piece of clothing ⇒ shirt, pants, socks, or hat
  • There are 3 possible colors ⇒ purple, blue, or orange

<u>To find the total number of outcome :</u>

Total outcomes ⇒ (number of clothes) × (number of colors)

⇒ 4 × 3 = 12

 Therefore, there will be 12 different possibilities.

<u>The 12 different outcomes are :</u>

⇒ Purple shirt, blue shirt, orange shirt

⇒ Purple pants, blue pants, orange pants

⇒ Purple socks, blue socks, orange socks

⇒ Purple hat, blue hat, and orange hat.

Now, the probability that you'll end up with an  orange hat if you choose on random of 12 possibilities ⇒ No.of orange hats / Total no.of outcomes.

∴ P(orange hat) = 1 / 12

D. 9 + y = 6x and 6x - y = 9 has an infinite number<br> of solutions.<br> True<br> False
zepelin [54]

Answer:

True

Step-by-step explanation:

9 + y = 6x -> y = 6x - 9

6x - y = 9 -> y = 6x - 9

A solution occurs whenever there is a value for x that can solve both equations.

The equations are the same.

If you plotted them on a graph they would overlap and there would be a straight diagonal line going on forever.

So there are infinitely many solutions.
