Event: Probability: A. Too much enamel 0.18 B. Too little enamel 0.24 C. Uneven application 0.33 D. No defects noted 0.47
let P(AC) = x, P(BC) = y, then P(A) + P(B) + P(C) - (x+y) = 1-0.47 = 0.53 x+y = 0.22
3. The probability of paint defects that results to <span>an improper amount of paint and uneven application? </span>
P(A U B U C) = 0.53
4. <span>the probability of a paint defect that results to</span>
<span>the proper amount of paint, but uneven application?</span>
P(C) - P(AC) - P(BC) = 0.47 - 0.22 = 0.25
A and B are disjoint so P(ABC) = 0, but you can have P(AC) and P(BC). you can't compute these separately here, but you can compute P(AC) + P(BC). By the way, P(AC) eg is just an abbreviated version of P(A∩C).
Hello!
The words at least means that the worker needs to work 8, 9 or 10 hours. We can add probabilities, so we will add .6 (for those working 8 hours), .15 (for those working 9 hours) and .08 (for those working 10 hours) to get a total probability of .83.
Hope this helps!

Answer:</h2><h2>
The cost of ketchup bottle, x = 2.89</h2><h2>
The cost of mustard bottle, y = 1.59</h2>
Step-by-step explanation:
Let the ketchup be represented as x and mustard as y
Briana bought 3 bottles of ketchup and 2 bottles of mustard and for $11.85
3x + 2y = 11.85 ...(1)
Logan bought 2 bottles of ketchup and 5 bottles of mustard for $13.73.
2x + 5y = 13.73 ...(2)
Multiplying eq (1) by 2, we get
6x + 4y = 23.7 ...(3)
Multiplying eq (2) by 3, we get
6x + 15y = 41.19 ...(4)
Subtracting eq (3) from (4),
we get 11y = 17.49
y = 1.59, substitute it in eq(1), we get
x = 2.89
Therefore, the cost of ketchup bottle, x = 2.89
The cost of mustard bottle, y = 1.59
