The answer is 31/125 <span>≈ 0.25.</span>
To calculate this, we will use both addition rule and multiplication rule.
The addition rule is used to calculate the probability of one of the events from multiple pathways. If you want that only one of the events happens, you will use the addition rule. In this method, the possibilities of each event are added. So, we will use the addition rule to calculate<span> the probability that the teacher randomly picks either a caramel chocolate (1st event) or a dark chocolate (2nd event):
1. There are 16 caramel chocolates out of 50 chocolates in total. Thus, the probability that a caramel chocolate is picked is 16/50.
</span>2. There are 15 chocolates out of 50 chocolates in total. Thus, the probability that a caramel chocolate is picked is 15/50.<span>
ADDITION RULE:
16/50 + 15/50 = 31/50
The probability that teacher </span>picks either a caramel chocolate or a dark chocolate is 31/50.
The multiplication rule calculates the probability that both of two events will occur. In this method, the possibilities of each event are multiplied. So, we will use the multiplication rule to calculate the probability that the teacher distributes the chocolates among students (1st event) and that she randomly picks either a caramel chocolate or a dark chocolate (2nd event):
1. The probability that the teacher distributes the chocolates among students is 0.4 = 4/10.
2. The probability that teacher picks either a caramel chocolate or a dark chocolate is 31/50.
MULTIPLICATION RULE:
4/10 × 31/50 = 124/500 = 31/125 ≈ 0.25
Answer:
<h2>$352</h2>
Step-by-step explanation:
Find out the price of one bagel by dividing the price by the number of bagels:
350 Bagels = $168
1 Bagel = $0.48
475 Bagels = $209
1 Bagel = $0.44
0.48 > 0.44
This means the second bakery has the lower price.
Louis wants 800 bagels, so multiply the price by 800.
0.44 * 800 = $352
You can check it's lower by comparing it with the first bakery.
0.48 * 800 = $384
384 > 352
273.32 is the surface area. Hope this helps!
The number of songs is x so twice the nb of songs is 2x and 3 fewer than gives -3 so we obtain 2x-3
Answer:
Step-by-step explanation:
Bonnie deposits $70.00 into a new savings account.
The account earns 45% simple interest per year.
She neither added or removed from the savings account for 3 years.
We know that,
here,
i = interest,
P = principal = $70,
r = rate of interest = 45%,
t = time = 3 years,
Putting the values,
So the total amount will be,
