Add: (-2x² +3x +4) +(x² -4x -5) = (-2+1)x² +(3-4)x +(4-5) = -x² -x -1
Opp: -(3x² -x +1) = 3x² +x -1
Sub: (x² +3x -4) -(-2x² +4x -3) = (1-(-2))x² +(3-4)x +(-4-(-3)) = 3x² -x -1
Answer: 0.1
Step-by-step explanation:
Given
Bag-I has 2 blue,3 orange, 5 red
Bag-II has 4 Pink,10 blue, 6 brown
No of ways of choosing a blue marble from bag-I
Total no of ways of choosing a marble from bag-I
No of ways of choosing a blue marble from bag-II
Total no of ways of choosing a marble from bag-II
The probability that he will pull out a blue marble from each bag is
