Answer:
0.45% probability that they are both queens.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes
The combinations formula is important in this problem:
is the number of different combinations of x objects from a set of n elements, given by the following formula.
Desired outcomes
You want 2 queens. Four cards are queens. I am going to call then A,B,C,D. A and B is the same outcome as B and A. That is, the order is not important, so this is why we use the combinations formula.
The number of desired outcomes is a combinations of 2 cards from a set of 4(queens). So
Total outcomes
Combinations of 2 from a set of 52(number of playing cards). So
What is the probability that they are both queens?
0.45% probability that they are both queens.
A 4th degree polynomial will have at most 3 extreme values. Since the degree is even, there will be one global extreme, with possible multiplicity. The remainder, if any, will be local extremes that may be coincident with each other and/or the global extreme.
(The number of extremes corresponds to the degree of the derivative, which is 1 less than the degree of the polynomial.)
What fraction of the length is the width of the book
is 2:3
wqual because you round 0.6 to 1 and 0.4 to 0 so 2+1 is 3
Answer:
<u>D) x² - y = 10x + 25 + y</u>
Step-by-step explanation:
A relation only becomes a function if each x-value only has a single y-value as the answer.
<u>Evaluating</u>
- A and B cannot be the answers as each value will get 2 answers
- C will also not be the answer as y² means at least 2 answers will be given
- <u>D</u> is the best option as each inputted x-value will get an answer of a single y-value
