<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.

The correct angle measures are m/JKL = 37° and mZKLM = 126°. Option A and C
<h3>How to determine the angle</h3>
Given that;
∠ K = (4x + 5)°
∠ J = 6x + 1
∠ L = 8x + 30 = 180 ( angles on a straight line)
Note that the sum of the angles of a triangle is 180°
∠ K + ∠ J + ∠ L = 180
6x + 1 + 4x + 5 + 8x + 30 = 180
collect like terms
18x = 180 - 36
18x = 144
Make 'x' the subject
x = 144/ 18
x = 8
Substitute the values
∠ JKL = (4x + 5)° = 4(8) + 5 = 37°
∠KJ L = (6x + 1)° = (6(8) + 1) = 49°
∠ KLM = 8x + 30 = 8(8) + 30 = 94°
∠ JLK = 8x + 30 = 180 = 180 - 94 = 86°
Thus, the correct angle measures are m/JKL = 37° and mZKLM = 126°. Option A and C
