Answer:
C is the correct option
Step-by-step explanation:
To find the probability of P(a or b) we will use the formula:
P(a or b)= P(a)+ P(b) - P(a-b)
Now put the given values in the formula:
P(a or b)= 0.60+0.25-0.15
P(a or b)=0.85 - 0.15
P(a or b)= 0.70
Thus the correct option is C....

Step-by-step explanation:
Answer:
5x³y² - 2x²y³ - 7y²
Step-by-step explanation:
Step 1: Write expression
(3x³y² + 5x²y³ - 6y²) - (7x²y³ - 2x³y² + y²)
Step 2: Distribute negative
3x³y² + 5x²y³ - 6y² - 7x²y³ + 2x³y² - y²
Step 3: Combine like terms (x³y²)
5x³y² + 5x²y³ - 6y² - 7x²y³ - y²
Step 4: Combine like terms (x²y³)
5x³y² - 2x²y³ - 6y² - y²
Step 5: Combine like terms (y²)
5x³y² - 2x²y³ - 7y²
