Answer:
$133.9
Step-by-step explanation:
<em>I believe the unit being used in the problem above is dollar ($).</em>
The problems above can be easily solved by using <em>multiplication operation </em>and <em>addition operation </em>afterwards.
Given: Bermuda sod = <em>$2.25 per piece</em>
Zoysia sod = <em>$3.32 per piece</em>
Let's solve for the cost of buying the Zoysia sod.
20 pieces x $3.32 per piece = $45 dollars
The total cost of the Zoysia sod that Becky will buy is $66.4.
Next, let's solve for the cost of buying the Bermuda sod.
30 pieces x $2.25 per piece = $67.5
The total cost of the Bermuda sod that Becky will buy is $67.5.
Let's get the total cost.
$66.4 + $67.5 = $133.9
<em>It will cost Becky $133.9 to buy 20 pieces of Zoysia sod and 30 pieces of Bermuda sod.</em>

Step-by-step explanation:
Assuming that all the grapes have the same probability of being randomly picked:
<h3>
How to find the probabilities?</h3>
We know that there are 8 green grapes and 15 red grapes on the bowl, so there is a total of 23 grapes.
a) Here we need to find the probability that both grapes are green. Remember that the probability of getting a green grape is equal to the quotient between the number of green grapes and the total number of grapes, this is:
P = 8/23
But then he must take another, because he already took one, the number of green grapes is 7, and the total number of grapes is 22, so for the second grape the probability is:
P' = 7/22.
The joint probability is the product of the two individual probabilities:
prob = (8/23)*(7/22) = 0.11
b) For the first green grape we know that the probability is:
P = 8/23
Then he must get a red grape. There are 15 red grapes and 22 grapes in total, so the probability is:
P' = 15/22
Then the joint probability is:
prob = (8/23)*(15/22) = 0.24
