Answer: n=7

Step-by-step explanation:

We are given an equation : \dfrac{35}{49}=\dfrac{5}{n}

To find n , we multiply n on both the sides , we get

\dfrac{35}{49}\times n=\dfrac{5}{n}\times n

\Rightarrow\ \dfrac{35n}{49}=5

Now, we multiply 49  on both sides , we get

\dfrac{35n}{49}\times49=5\times49

35n=245

Divide both sides by 35, we get

\dfrac{35n}{35}=\dfrac{245}{35}\\\\\Rightarrow\ n=7

A component is assembled in a four-step process. The probability of making a defect in step 1 is 10%; in step 2, 20%; in step 3,
rjkz [21]

Answer:

0.37072

Step-by-step explanation:

Let A be the event that step 1 is defective (P(A) = 10%), B the event that step 2 is defective(P(B) = 20%), C the event that step 3 is defective (P(C) = 8%), D the event that step 4 is defective(P(D) = 5%). Let us suppose that the occurance of a failure at any step is indepent of the other steps.

Recall the following properties

P(A) = 1- P(A^c)

(A\cup B )^c = A^c \cap B^c)

And given A, B, C, D independent , then

P(A\cap B \cap C \cap D) = P(A)P(B)P(C)P(D)

REcall that if the a set of events A,B,C,D are independent, their complements are also indepent.

Since we are asked for the probability of a defective item, this means that at least one of the steps is defective. Then, we are asked for the following probability:

P(A\cup B \cup C \cup D) = 1 - P((A\cup B \cup C \cup D)^c) = 1 - P(A^c \cap B^c \cap C^c \cap D^c ) = 1 - P(A^c)P(B^c) P(C^c) P(D^c) = 1-(1-P(A))(1-P(B))(1-P(C))(1-P(D))

= 1-(0.9)(0.8)(0.92)(0.95) = 0.37072
