The probability that it is pink or canvas is 0.9
Step-by-step explanation:
Let us revise the meaning of "or" , "and" on probability
:
- The use of the word "or" means that you are calculating the probability that either event A or event B happened. Both events do not have to happen
- The use the word "and", means that both event A and B have to happen
The addition rules are:
- P(A or B) = P(A) + P(B) ⇒ mutually exclusive (events cannot happen at the same time)
- P(A or B) = P(A) + P(B) - P(A and B) ⇒ non-mutually exclusive (if they have at least one outcome in common)
Anna is shopping for a new backpack
∵ The probability that the backpack is pink is 0.7
∴ P(pink) = 0.7
∵ The probability that it is canvas is 0.7
∴ P(canvas) = 0.7
∵ The probability that it is pink and canvas is 0.5
∴ P(pink and canvas) = 0.5
Substitute the values above in the rule below
∵ P(pink or canvas) = P(pink) + P(canvas) - P(pink and canvas)
∴ P(pink or canvas) = 0.7 + 0.7 - 0.5
∴ P(pink or canvas) = 0.9
The probability that it is pink or canvas is 0.9

The common factor of the expression is .
In the given question,
The given expression is .
We have to find a common factor for the expression that has a coefficient other than 1 and that contains at least one variable and also explain how you found the common factor.
Then we have to Rewrite the expression using the common factor you found in Part A.
We have to find the common factor of the given equation.
We can find the common factor after common the terms that are same in both term.
The equation is .
We can write the equation as
As we can see in the equation that is common from both term.
So the equation should be
We can write it as
So the common factor of the given expression is .
Now we rewriting the expression.
Since the common factor is .
So we can rewrite the expression by multiplying the common factor to .
So
Hence, the common factor of the expression is .
