( I'm assuming it's supposed to say 3 jelly-filled, 4 lemon-filled, and 17 custard-filled since there are only 24 donuts)

this means that 3 out of 24 are jelly (3/24)
4 out of 24 are lemon (4/24)
and 17 out of 24 are custard (17/24)
the probability of eating a custard donut is then 17/24
now there are 23 donuts left, and 16 are custard. the probability of eating a custard donut is now 16/23. however, the probability of both of these happening is found by multiplying these 2 separate probabilities:

17/24 × 16/23 = 272/552
this probability is then simplified:
(272÷8)/(552÷8)= 34/69
so, the answer is 34/69, which is about a 49.3% chance

chef ollie has a community garden.she uses 2/6 of the farmland to grow beets and 1/6 of the farmland to grow kale. how much of t
Lorico [155]

Answer:

1/2 of farm land left.

Step-by-step explanation:

  Ok so we know that Chef Ollie has a community garden. And that she uses \frac{2}{6} of the farmland to grow beets. The denominator 6 lets you know immediately that the land is divided into equal 6 pieces. We also know that Chef Ollie uses another \frac{1}{6} of the farmland to grow kale.

  Because the we need to find out how much land Chef Ollie has left, we need to subtract the amount she used from the whole. Before we can do that we must add up the total amount of used land, and since the denominators are the same we can directly add and subtract with having to change the denominator.

Step 1: Write down important numbers.

\frac{2}{6}, \frac{1}{6},

Step 2: Add those numbers together.

\frac{2}{6} + \frac{1}{6} = \frac{3}{6} or \frac{1}{2}

Step 3: Write an expression/equation.

\frac{6}{6} - \frac{3}{6} \\or\\1 - \frac{1}{2}

Step 4: Solve

=    \frac{3}{6}\\or\\\frac{1}{2}

(can be written both ways)

  And you get your answer: After Chef Ollie has used \frac{2}{6} to grow beets and \frac{1}{6} to grow kale, she has \frac{1}{2} of her farmland left untouched.

  To represent this you could draw a circle divided in 6 pieces and shade 3 of them, or simply draw a circle and shade half. As well as drawing a rectangle and dividing it into 6 pieces, shading 3, or draw a rectangle, and shade half.

You are welcome ;) .
