Answer:

x = 3

y = 8

Since it gives you x, you need to plug in the number given for it into the equation:

y = 3x - 1

y = 3(3) - 1

y = 9 - 1

y = 8

Elizabeth brought a box of donuts to share. There are two-dozen (24) donuts in the box, all identical in size, shape, and color.
pashok25 [27]

The probability of selecting two jelly-filled donuts in a row is 1/ 22

<h3>What is probability?</h3>

Probability is simply the chance that a given event will occur.

It is also the ratio of the number of outcomes in a set of equally likely outcomes that produce a given event to the total number of possible outcomes.

From the information given, we have that the donuts are:

  • 6 are jelly-filled
  • 10 are lemon-filled
  • 8 are custard-filled

Note that two jelly - filled donuts were taken without replacement

Probability( 2 jelly -filled donuts) = 6 / 24 × 4/ 22 = 24/ 24 × 22 = 1/ 22

Thus, the probability of selecting two jelly-filled donuts in a row is 1/ 22
