Answer: variable is distributed normally, then approximately two-thirds of the population will within plus or minus one standard deviation of the mean
Step-by-step explanation:
The standard deviation is calculated as the square root of variance by determining each data point's deviation relative to the mean. If the data points are further from the mean, there is a higher deviation within the data set; thus, the more spread out the data, the higher the standard deviation.
Answer + Explanation:
The Monty Hall problem is a famous problem in conditional probability and reasoning using Bayes' theorem.
How to explain the probability?
In the problem, you are on a game show, being asked to choose between three doors. Behind each door, there is either a car or a goat.
You choose a door. The host, Monty Hall, picks one of the other doors, which he knows has a goat behind it, and opens it, showing you the goat.
You know, by the rules of the game, that Monty will always reveal a goat. Monty then asks whether you would like to switch your choice of door to the other remaining door.
In conclusion, the solution is that switching will let you win twice as often as sticking with the original choice.
Perimeter is the addition of all 4 sides and a square as all the same sides. so every side will be the same. so if you divide 216 by 4 you get 54. you can check this by adding 54+54+54+54=216 or 54x4=216
The perimeter is the sum of all four sides so it would be 2+2+5+5=14
