A pair of 7 sided dice are tossed. What is the probability that at least one of the dice has a value greater than or equal to 4?
Answers
Answer:
40/49
Step-by-step explanation:
One way to answer this is to ask the opposite question.
What is the probability that neither will show a number 4 or more?
That would mean BOTH have to each be a 3 or less.
For the first die to show 3 or less --> probability = 3/7
For the second die to show 3 or less --> probability = 3/7
For them BOTH to show 3 or less --> probability = 3/7 * 3/7 = 9/49
Probability a thing happens + probability it doesn't happen = 1. Always.
Prob(both dice 3 or less) + Prob(at least one die 4 or more) = 1
So, Prob(at least one die 4 or more) = 1 - Prob(both dice 3 or less)
= 1 - 9/49
= 49/49 - 9/49
= 40/49
The probability of having atleast one dice with a value greater than or equal to 4 is 0.8163
Using a sample space which is attached below :
Recall :
Probability = required outcome / Total possible outcomes
Required outcomes = 40
Total possible outcomes = 7² = 49
The probability of having atleast one dice with a value greater than or equal to 4 will be :
Probability = 40 / 49 = 0.8163

What are the advantages and disadvantages of bar chart
Answers
Answer:
Advantages:
● Bar charts are pretty easy to interpret, and there's a very clear relationship between size and value that allows easy comparison.
● They're simple to make and most people have experience creating and understanding them from school.
● They can help in presenting very large or very small values more emphatically.
Disadvantages:
● Bar charts that attempt to represent wide ranges of numbers will struggle to efficiently communicate their message. For example, a bar chart for the numbers 5, 6, 10 and 378 will lend extreme visual weight to the highest value and make the relative values of the other measurements appear irrelevant. An alternative to this would be creating an adjusting scale for the bars, but this complicates the visual aspect of the presentation and breaks the intuitive sense that size correlates directly to value.
● Bar graphs tend to be locked into a particular data set, making it hard to show multiple values or changes over time unless the chart is modified, such as by making the bars layered and three-dimensional.

(-60/11,111/11)
Step-by-step explanation:
Solving simultaneously, 4x - 3y=6 -3(6x + y=42) then it becomes, 4x - 3y=6
-18x - 3y= 126 subtracting the two equations, 22x= -120, x= -60/11 and y = 111/11
.
Answer:
(-0.5, 1)
Step-by-step explanation:
4x - y = -3 ----------------------(I)
-6x + 3y = 6 -------------------(II)
Multiply equation (I) by 3 and then add. So, y will be eliminated and you can find the value of x.
(I) * 3 12x - 3y = -9
(II) -6x + 3y = 6 {Now, add}
6x = -3
x = -3/6
x = - 0.5
Plug in x = -0.5 in equation(I)
4*(-0.5) - y = -3
- 2 - y = -3
-y = - 3 + 2
-y = -1
y = 1

Hunter surveyed 200 of the students in his school about their favorite color. 66 students said their favorite color was blue. What percentage of the surveyed students said their favorite color was blue?
Answers
The percentage of the surveyed students who said their favorite color was blue is 33%
What are percentages?A percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate the percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred. The word percent means per 100. It is represented by the symbol “%”
Given here: Hunter surveyed a total of 200 students.
Also students with blue as their favorite color are 66
We know percentage is ratio of the quantity involved over the whole multiplied by 100
Thus the number of students with blue as their favorite color in percentage terms is = 66/200 × 100
= 33%
