Can someone help me with this.In a school, 30% of the students have hazel eyes. Find the experimental probability that in a group of 4 students, at least one of them has hazel eyes. The problem has been simulated by generating random numbers. The digits 0-9 were used. Let the numbers "6". "7", and "8" represent the 30% of students with hazel eyes. A sample of 20 random numbers is shown.

Experimental probability that in a group of 4 students, at least one of them has hazel eyes is 85%.
What is experimental probability?
The experimental probability of an event occurring is the number of times that it occurred when the experiment was conducted as a fraction of the total number of times the experiment was conducted.
According to the question
In a school, 30% of the students have hazel eyes.
The number of hazel eyes in data is 17
The total number of data sets are 20.
Experimental probability = × 100%
= 85%
Hence, experimental probability that in a group of 4 students, at least one of them has hazel eyes is 85%.

So all I did is multiply 22x10
Final answer:
To determine the total number of students in your grade, use the equation (1/10)x = 22 and solve for x by multiplying both sides of the equation by 10.
Explanation:
To find out how many students are in your grade, you can set up an equation using the theoretical probability and the number of students who tried out for the school play. The equation can be written as: (1/10)x = 22, where x represents the total number of students in your grade. To solve for x, you can multiply both sides of the equation by 10 to get rid of the fraction. This gives you x = 220, so there are 220 students in your grade.

with a little algebra we can reorganize the equation and solve for length...
A = L x W
A/W = L
So the statement divide the area by the width is TRUE.
Area = length × width
Divide width on both sides
Area/width = length × width/ width
Flip the equation
Length = Area/width

Answer:
{-2/7, 2/7}
Step-by-step explanation:
Here you're being asked to solve the given equation 49w^2-4=0 for w with the hint that the solutions are fractions.
49w^2-4=0 is the product of the sum and difference of two squares:
(7w - 2)(7w + 2) = 0
Setting each factor equal to zero and solving for w, we get:
{-2/7, 2/7} as the solutions.

3912.99/15.9
= (391299 * 10)/(159 * 100)
= (391299)/(1590)
= 246.10
So the answer that comes out from the division of the two numbers given in the question is 246.10. I hope i have described the full process and it has helped you to understand the way these kind of problems need to be tackled.
