Answer:
What type of question is this
The probability of winning when there is only one prize, is:
P = 1/2,790,720
<h3>
How to find the probability?</h3>
Each ticket has 6 different numbers, in order, from 1 to 20.
- The first number has 20 options.
- The second number has 19 options (because the numbers can't repeat).
- The third number has 18 options, and so on.
The total number of possible combinations is given by the product between the numbers of options, so there are:
C = 20*19*18*17*16*15 = 27,907,200 possible tickets.
So, if Trina purchases 10 tickets, she has a probability of 10 out of 27,907,200 winning (when we assume that there is only one prize)
Then the probability is:
P = 10/27,907,200 = 1/2,790,720

Answer: standard deviation
is a measure of the amount of variation or dispersion of a set of values.[1] A low standard deviation indicates that the values tend to be close to the mean (also called the expected value) of the set, while a high standard deviation indicates that the values are spread out over a wider range.The standard deviation of a random variable, statistical population, data set, or probability distribution is the square root of its variance. It is algebraically simpler, though in practice less robust.The standard deviation is given by the formula: s means 'standard deviation'. S means 'the sum of'. Now, subtract the mean individually from each of the numbers given and square the result.
Step-by-step explanation :percentage area
i've never really heard of this but my sister just breifed me and this is what i could get
to calculate percentage area Find the percentage of a portion of an object by dividing the area of the portion by the area of the whole original object. Multiply the length times the width of the original piece to calculate its area in square inches, feet or centimeters
i hope it hrlps please mark me brainliest :)
Answer:
24%
Step-by-step explanation:
The total amount of guests is 50. 12/50 saw Wonder Woman 1984. To turn that into a percentage you have to divide 12 by 50 which is .24. Therefore, 24% of the guests saw Wonder Woman 1984.
