There are 3 boxes. First box contains 100 components of which 20 % are defective, second box contains 200 components of which 25
natali 33 [55]

Answer:

Step-by-step explanation:

Given that there are 3 boxes. First box contains 100 components of which 20 % are defective, second box contains 200 components of which 25 % are defective, third box contains 300 components of which 40 % are defective.

Box is selected randomly and from this box one component is selected randomly. The chosen component turned out to be defective.

Here A1, A2 and A3 events from drawing I, II and III box are mutually exclusive and exhaustive

B = The drawn ball is defective

Required probability

a) second box = P(A2/B)

=\frac{P(A_2B)}{P(A_1B+P(A_2B+P(A_3B}

(by Bayes theorem of conditional probability)

= \frac{\frac{1}{3} 0.25}{\frac{1}{3} 0.20)+\frac{1}{3} 0.25)+\frac{1}{3} 0.40)} \\=\frac{25}{85} \\=\frac{5}{17}

b) third box = P(A3/B)

=\frac{\frac{1}{3} 0.40}{\frac{1}{3} 0.20)+\frac{1}{3} 0.25)+\frac{1}{3} 0.40)} \\=\frac{40}{85} \\=\frac{8}{17}

Answer:

Since the sum of the angles equal to 720, you have to add all the angles to add to 720 and then solve for x, in which would look like this (x+2)+(x-4)+(x+6)+(x-3)+(x+7)+(x-8)=720, which is simplified to (6x)=720, in which will make x=120. Next, since its angle E, you plug in tha x value, (120+6), in which the ANSWER IS 126 DEGREES

Step-by-step explanation:

Hope this help ^w^
