Sua matemática seria:10.8 * 3 = 32.4
32.4 + 32.4 + 10.8 + 10.8 = 86.4
86.4 * 130 = 11,232
11,232 - 10,000 = 1,232Você precisará de mais 1,232 tijolos para concluí-lo.
Eu espero que isso ajude :)

Human visual inspection of solder joints on printed circuit boards can be very subjective. Part of the problem stems from the nu

Basile [38]

Answer:

a) 0.8841

b) 0.0435

Step-by-step explanation:

A : the set of joints deemed defective by inspector A.

B: the set of joints deemed defective by inspector B.

U: the set of all joints.

The problem says |A|=724, |B|=751, |A∪B|=1159, |U|=10000. Hence, with the help of Venn diagram we can answer the following:

Part a)

This asks for the number of joints that are ∉(A∪B).

hence,

P (∉(A∪B)) :

$\frac{10000-1159}{10000} \\\\=0.8841$

part b)

This asks for the number of joints that are in B but not in A, which Is represented as the set B−A

$= \frac{|B| - |AandB| }{|U|}\\\\= \frac{751-316 }{10000}\\\\= 0.0435$
