A bowl has 9 green grapes and 13 grapes. Henry randomly chooses a grape, and eats it, and then choose a another grape What is th

Sunny_sXe [5.5K]

Answer:

$\frac{72}{462}$ or $\frac{12}{77}$ (simplified)

Step-by-step explanation:

Based on the information provided within the question it can be said that in order to calculate the probability of both grapes being green we need to find the probability of each grape being green separately and then multiply those probabilities together

In the first choice, there are a total of 22 grapes (9+13), 9 of which are green. Therefore the probability of the first chosen grape being green is $\frac{9}{22}$

In the second choice,since we removed one grape there is now a total of 21 grapes (22-1), 8 of which are green. Therefore the probability of the second chosen grape being green is $\frac{8}{21}$

Now we multiply both probabilities together to calculate the probability that both grapes are green in a sequence.

$\frac{9}{22} * \frac{8}{21} = \frac{72}{462} or \frac{12}{77}$

Sara sells homemade blueberry jelly (b) and strawberry jam (s) at the farmer's market. It is the end of berry picking season, so

Diano4ka-milaya [45]

System of inequalities representing given scenario is as follows

x + y ≤40

5x + 4y ≥ 120

<h3>Solution:</h3>

Given that Sara sells homemade blueberry jelly (b) and strawberry jam (s) at the farmer's market. She has enough berries for no more than 40 jars.

The blueberry jelly sells for $5 per jar,

And the strawberry jam sells for $4 per jar.

Sara's goal is to make at least $120

Need to write system of inequalities for above scenario.

Let’s assume number of jars of blueberry jelly be represented by variable “x”

And assume number of jars of strawberry jam be represented by variable “y”

Let’s create first inequality

As it is given that Sara has enough berries for no more than 40 jars, so total number of jars cannot be more than 40.

=> Number jars of blueberry jelly + number of jars of strawberry jam ≤40

=> x + y ≤ 40 ------(1)

Now let’s create second inequality

Selling Price of 1 blueberry jelly = $5

So Selling Price of "x" blueberry jelly $=x \times 5=5 x$

Selling Price of 1 strawberry jam = $4

So Selling Price of "y" strawberry jam = $\$ 4 \times \mathrm{y}=4 y$

So amount generated by selling x blueberry jelly and y strawberry jam = 5x + 4y

And as Sara’s goal is to generate at least $120, so amount generated by selling “x” blueberry jelly and “y” strawberry jam must be greater than $120

=> 5x + 4y ≥ 120 ------ (2)

Hence system of inequalities representing given scenario is as follows :

x + y ≤40

5x + 4y ≥ 120
