P(A) = 0.8, P(B) = 0.55 and P(A and B) = 0.35.<br> What is P(A or B)?
Likurg_2 [28]
<h3>Answer:  1</h3>

Work Shown:

P(A or B) = P(A) + P(B) - P(A and B)

P(A or B) = 0.8 + 0.55 - 0.35

P(A or B) = 1.35 - 0.35

P(A or B) = 1

A probability of 1 means there is 100% certainty the event happens. This must mean that there are only possible outcomes are: either event A happens, or B happens, or possibly both A and B happen simultaneously.

5(x+4)-3x+3=5 solve for x
Elena L [17]

Answer: X= -9

Step-by-step explanation:

Multiply the 5 by x+4 then copy the -3x+3=5. It will be 5x+20-3x+3=5.

Then subtract or add the like terms

5x-3x and 20+3. It will be 2x+23=5

Then add -23 to both sides

It will be 2x+23-23=5-23 then solve it will be 2x=-18 then divide both sides by 2 to find the value of x

2x/2=-18/2 then the final answer is x= -9. I hope it help
