The equivalents are ...

  • A. 10 · (4 + 3)
  • B. 10 · 3 + 10 · 4
  • C. (3 + 4) · 10

_____

The expression in D evaluates to 30+4 = 34, not 10·7 = 70.

In A, (4 + 3) is equivalent to (3 + 4) by the commutative property of addition. The commutative properties of multiplication and addition allow you to swap the order of the operands with no effect on the result.

In B, 10·3 +10·4 is equivalent to 10·(3+4) by the distributive property of multiplication over addition.

In C, (3+4)·10 is equivalent to 10·(3+4) by the commutative property of multiplication.

anna is shopping for a new backpack. The probability that the backpack is pink is 0.7, and teh probability that it is canvas is
harkovskaia [24]

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
