You have the numbers 1-24 written on a slip of paper if you choose one slip at random what is the probability that you Will Not select a number which is divisible by 3

Answers

Answer 1

Answer:

Answer:

$(2)/(3)$ .

Step-by-step explanation:

Given : You have the numbers 1-24 written on a slip of paper if you choose one slip at random .

To find : what is the probability that you Will Not select a number which is divisible by 3.

Solution : We have given that numbers from 1 to 24

Numbers divisible by 3 area 3,6,9,12,15,18,21,24.

There are 8 numbers which are divisible by 3

So, numbers which are not divisible by 3 are 24 -8 =16.

Probability of number which are not divisible by 3 = $(16)/(24)$ .

Probability of number which are not divisible by 3 = $(2)/(3)$ .

Therefore, $(2)/(3)$ .

Answer 2

Answer: 3,6,9,12,15,18,21,24 are div by 3. thats 8 numbers out of 24. 8/24=1/3. 3/3-1/3 is 2/3. 2/3=66.67%

Probability theory predicts that there is a 9% chance of a water polo team winning any particular match. If the water polo team playing two matches is simulated 10,000 times, in about how many of the simulations would you expect them to win exactly one match?A. 8281
B. 1638
C. 81
D. 819

Answers

The result is B. 1638.

To calculate this, we will use both an addition and a 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. The multiplication rule calculates the probability that both of two events will occur.
First, there are two possibilities for winning exactly one match:
1. To win the first match and lose the second one.
2. To lose the first match and win the second one.

9% = 0.09 is the probability of winning. The probability of losing is 1-0.09 = 0.91. To calculate the probability of winning the first match and losing the second one and vice versa, we will use the multiplication rule:
1. 0.09 × 0.91 = 0.0819
2. 0.91 × 0.09 = 0.0819

We want to either one of these events to happen, so using the addition rule, we have:
0.0819 + 0.0819 = 0.1638

In 10,000 matches:
0.1638 × 10,000 = 1,638

Evaluate [3(5 + 6) + 2] ÷ 7

Answers

[3(5 + 6) + 2] ÷ 7= 35/7

35/7=5

Answer:

Step-by-step explanation:

[3(5 + 6) + 2] ÷ 7

(5 + 6) = 11

[3(11) + 2] ÷ 7

3 x 11 = 33

[33 + 2] = 35

[35] ÷ 7 = 5

Thus the answer, 5

Bill makes leather shoes. He charges $45 for a pair of women's shoes and $50 for a pair of men's shoes. He sells x pairs of women’s shoes and y pairs of men’s shoes each week and earns a total income of $2,500. This situation can be represented by the equation . If Bill has no female customers during a particular week, he needs to sell pairs of men’s shoes to earn his weekly income of $2,500.

Answers

Hello,

Let's
x pairs of women’s shoes sold
y pairs of men’s shoes sold
R(x,y)=45*x+50y=2500 (each week)

Or the week, =0 =>50*y=2500=>y=500.
