Answer:
1/1000
Step-by-step explanation:
The probability of two independent events A, B (independent = events that do not depend on each other) is given by the product of the individual probabilities of A and B:
(1)
In this problem, the single event is "getting a 3" when extracting a random number between 1 and 10.
The total number of possible outcomes is
n = 10
While the number of succesfull outcomes (getting a 3) is only one:
So, the probability of drawing a 3 in 1 draw is
Then, we want to find the probability of getting three "3" in 3 consecutive generations. These events are independent events, so we can use rule (1) to find the total probability, and we get:
The probability would be 0.1971.
We will calculate a z-score for each end of this interval.
z = (X-μ)/σ
For the lower limit:
z = (1100-1050)/218 = 50/218 = 0.23
For the upper limit:
z = (1225-1050)/218 = 175/218 = 0.80
Using a z-table (http://www.z-table.com) we see that the area under the curve to the left of, less than, the lower limit is 0.5910. The area under the curve to the left of, less than, the upper limit is 0.7881. To find the area between them, we subtract:
0.7881 - 0.5910 = 0.1971
The answer is A in my opinion
Answer:
$260
Step-by-step explanation:
0.06 x 200 = 12
12 x 5 = 60
200 + 60 = 260
Answer: 3
Step-by-step explanation:
To calculate the volume of a rectangular box, first measure its length, width, and height. Be sure to use the same units, like inches or centimeters, for all 3 measurements! Then, simply multiply the 3 measurements together using the formula Volume = Length × Width × Height.
