For X = 1,
P(~A and B)
or
P(A and ~B) =
0.6 * 0.3 + 0.4*0.7 = 0.46
Oh, I think I see, the universe for P(A and B) is first
or
second file
while P(~A and B) or P(A and ~B) the universe is first, second or no

Answer:
x=−4/3 or x=−3/2
Step-by-step explanation:
Let's solve your equation step-by-step.
6x2+17x+12=0
Step 1: Factor left side of equation.
(3x+4)(2x+3)=0
Step 2: Set factors equal to 0.
3x+4=0 or 2x+3=0
x=−4/3 or x=−3/2
Answer:

Answer:
Distribute the 3 to x + 2, and distribute the 5 to (2x – 3).
Step-by-step explanation:
Given
Required
Reasonable first step
The reasonable first step is to open the brackets; i.e. distribute 3 to its bracket and 5 to its bracket.
This gives:
<em>Then the solution can be continued</em>
30xt^3y is equivalent to 5(6xt3y)
