$\huge\boxed{Hello!}$ I can help you with joy! :)

We are asked to multiply -7 by (1+3x)

All we have to do is multiply -7 by 1 and 3x:

-7-21x

I have used the Distributive Property to solve this problem.

Find P(A or B or C) for the given probabilities. Upper P left parenthesis Upper A right parenthesis equals 0.34 comma Upper P

otez555 [7]

Answer:

$P(A \cup B \cup C)=0.48$

Step-by-step explanation:

Given the following probabilities for events A and B

$P(A)=0.34\\P (B )= 0.23\\ P (C )= 0.12\\ P(A \cap B )= 0.11\\ P (A \cap C )= 0.04\\ P (B \cap C )= 0.07\\P(A \cap B \cap C)=0.01$

We want to find P(A ∪ B ∪ C).

Using the inclusion/exclusion formula for the union of three events:

P(A ∪ B ∪ C) = P(A) + P(B) + P(C) − P(A ∩ B) − P(A ∩ C)−P(B∩C)+P(A∩B∩C).

$P(A \cup B \cup C)=0.34+0.23+0.12-0.11-0.04-0.07+0.01\\P(A \cup B \cup C)=0.48$

Therefore, P(A or B or C) = 0.48

4a - 5b + 6ab - 8b – 3a =

andreyandreev [35.5K]

Write the thing spaced out:

4a -5b +6ab -8b -3a
The signs (+,-) are assigned to the numbers it is in front of.

We minus the "like" terms:
4a - 3a = 1a
-5b - 8b = -13b
+6ab = +6ab

Put them all together:
1a - 13b + 6ab

The answer for, "4a - 5b + 6ab - 8b - 3a" = "1a - 13b + 6ab"
