Well, first you would add up how many objects you have to select from
9 democrats + 7 Republicans + 3 Independents = 19 total people
so then you would put how many people you can have over that number
so since we don't want any Democrats it would be 10/19 (.52)
and that tells you the chances of not picking one the first time
then, since that person cannot be selected again, we remove them from the pool, making it only 18 people to pick from and 9 people you want picked so once again you put 9/18 (.50), then you take those, (in decimal form) and multiply them (.26) then convert it to a fraction by moving the decimal to the right two and have 26% chance of no Democrats <span />
Answer:
The correct answer will be "1.60 hours".
Step-by-step explanation:
Within this test case, let's suppose that the bookstore had been closed on Sundays every other day while there were a total of 5 Sundays throughout the month of thirty days, thus effectively.
Months = 30
Number of sundays = 5
⇒ 
⇒ 
⇒ 
As we know, the total spend time will be 40 hours, then
⇒ 
On putting the estimated values, we get
⇒ 
⇒ 
The probability of 1 number showing up out of 20 is 1/20
The probability of 3 different numbers showing up would be 3/20
Answer: 3/20
Step-by-step explanation:

in we have x = 11
put the value of x in equation


so x = 11√3
Hope it helps
Answer:
C
Step-by-step explanation:
The zeros of the function is the roots and solutions. To find them, factor the equation into two binomials.

To solve, set each binomial to 0 and solve for x.
x+6 = 0
x = -6
x-5=0
x=5
