<h3>What is Probability?</h3>
Probability helps us to know the chances of an event occurring.
Dependent events are those events in which the outcome of the first event affects the outcome of the second event. The statement that is correct about the dependent event is that the probability of all dependent events can be calculated using the "OR" formula P(A+B) =P(A) +P(B)-P(A and B).
Hence, the correct option is A.

Answer:
His mistake is that he didn't multiply it -18 to the negative sign correctly. The negative sign and -18 have to multiply which turns -18 to a positive 18.
Step-by-step explanation:
-15-(-18)=-15 +(-18)
-15+18= -15 -18

Step-by-step explanation:
Multiply the radius by 2 to get the diameter. Multiply the result by π, or 3.14 for an estimation. That's it; you found the circumference of the circle
And then for diameter you have to Multiply the diameter by π, or 3.14. The result is the circle's circumference.
Answer:
42°
Step-by-step explanation:
angle 3 + angle 4 = 180° because together they make a straight line. So your equation should be 23x + 7x = 180. Add the like terms and you get 30x=180. Divide by 30 on both sides to get x. now you know that x=6. angle 4 = 7x. so you would multiply 7*6 to get 42. Thus angle 4= 42°
