Answer: 0.42 and 5 outcomes.
Step-by-step explanation:
i guess that carlos has a fair coin and a number cube.
the probability can be calculated as the number of outcomes that we want divided the total number of outcomes.
The coin has two possible outcomes, heads and tails, then the probability of getting heads is p1 =1/2
the number cube has 6 numbers, 5 of those 6 numbers are greater than 1, then the probability of getting a number greater than 1 is p2 =5/6
the joint probability is the product of those two:
P = 1/2*5/6 = 5/12 = 0.42
The combinations that include heads and number greater than 1 are 5 combinations:
Heads and 2
Heads and 3
Heads and 4
Heads and 5
Heads and 6.
Answer:
x ÷ 1/4
Step-by-step explanation:
<u>Concepts:</u>
- An expression a mathematical sentence that has at least two numbers and a minimum of one math operation (addition, subtraction, etc.) in it. An expression cannot have an = sign in it.
- A variable is an unknown, numerical value in an equation, often represented by the letter x.
<u>Solving:</u>
Let's translate the first part of the expression:
1. "A number"
- Since we're unaware of the number in this expression, we can mark it as a variable, x.
- This means that, so far for our expression, we only have the variable, "x".
2. "divided by 1/4"
- When we're dividing, we use the ÷ symbol to represent that operation.
- Now, let's put the first part of our expression with the second one: "x ÷ 1/4"
Therefore, the expression for this situation is x ÷ 1/4.
Answer: 3 step by step approach
Step-by-step explanation:
Since the Chancellor has to use a multi-stage sample to carry out the survey, he or she should carry it out step by step.
First, he or she should randomly sample some solar systems from the galaxy, then secondly sample planets within that solar system, and finally randomly sample countries within the selected planets
Which of the following sets represent A ∪ B? {6, 12} {2, 3, 4, 6, 8, 9, 10, 12} {1, 5, 7, 11} {2, 3, 4, 8, 9, 10}

<h3>AUB = { 2, 3, 4, 6, 8, 9, 10, 12}</h3>
<em><u>Solution:</u></em>
The complete figure of question is attached below
From figure,
Write all elements from set A
A = {3, 6, 9, 12}
Write all elements from set B
B = {2, 4, 6, 8, 10, 12}
AUB means A union B
AUB means set of all the numbers combined with set A and set B
Combine set A and B
AUB = { 2, 3, 4, 6, 8, 9, 10, 12}
Thus AUB is found
So every triangle has to add up to 180° so for 11 you would have to find out 180-84-36 which would be 60 and because there is a right angle (90°) or the little square you do 90-60 and get 30 then you do 180-86-30 getting you to your final answer of 64
