0
Step-by-step explanation:
Hello, please consider the following.
For any a and b real numbers we can write.
We apply this formula two times here, as below.
We have the coefficient of 1 for 
and the constant term is -1, so the sum of the coefficients is 0.
Thank you.
Answer:
Probability = 0.0288
Step-by-step explanation:
For the first draw.
There are total of 52 cards in a deck of cards and a total of 26 red cards in a deck of cards.
Probability of drawing a red= 26/52
Probability = 0.5
For the second draw. Actually the initial card drawn was replaced. Total number of face cards are 12.
Probability of drawing a face card = 12/52= 0.23076923
For the third draw .
There are 13 diamond cards in total.
Probability of a diamond = 13/52
Probability = 0.25
Probability of red,face, diamond= 0.5*0.23076923*0.25=0.028846
To four decimal place = 0.0288
Answer:
Step-by-step explanation:
We want to convert the interval [-1, ∞) to inequality notation using <em>x</em> as the variable.
The interval [-1, ∞) reads: "All real numbers between -1 and positive infinity."
In other words, it is all numbers greater than or equal to -1 and less than positive infinity.
Therefore:
Note that we do not use "or equal to" for the infinity as we can never really "equal" infinity.
