Answer:
1/2 for or against
Step-by-step explanation:
There is a six sided die so the chance of getting one side is 1/6.
To get the sum for 3 sides, just do 1/6 + 1/6 + 1/6 = 3/6 or 1/2.
 
        
             
        
        
        
4/10^2 = 0.04
which is equal to:
4x10^-2
As there are two digits behind the decimal point up to( and including the 4) thus the 10^-2
And as the digit is a 4 you multiply 10^-2 by 4
        
             
        
        
        
Correction:
Because F is not present in the statement, instead of working onP(E)P(F) = P(E∩F), I worked on
P(E∩E') = P(E)P(E').
Answer:
The case is not always true. 
Step-by-step explanation:
Given that the odds for E equals the odds against E', then it is correct to say that the E and E' do not intersect.
And for any two mutually exclusive events, E and E', 
P(E∩E') = 0
Suppose P(E) is not equal to zero, and P(E') is not equal to zero, then
P(E)P(E') cannot be equal to zero. 
So
P(E)P(E') ≠ 0
This makes P(E∩E') different from P(E)P(E')
Therefore, 
P(E∩E') ≠ P(E)P(E') in this case. 
 
        
             
        
        
        
Answer:
   t ≈ -2.014 or 3.647
Step-by-step explanation:
Add the opposite of the expression on the right side of the equal sign to put the equation into standard form.
   4.9t² -8t -36 = 0
You can divide by 4.9 to make this a little easier to solve.
   t² -(8/4.9)t -36/4.9 = 0
Now, add and subtract the square of half the x-coefficient to "complete the square."
   t² -(8/4.9)t +(4/4.9)² -36/4.9 -(4/4.9)² = 0
   (t -4/4.9)² -192.4/4.9² = 0 . . . . simplify
Add the constant term, then take the square root.
   (t -4/4.9)² = 192.4/4.9²
   t -4/4.9 = ±(√192.4)/4.9
   t = (4 ± √192.4)/4.9
   t ≈ {-2.014, 3.647}
