Probability of producing defective items in a workshop is 0.4.
If 20 products are picked at random, what is the probability that:
a) 2 will be defective b)at least 3 will be defective c) at most 4
will be defective
A factory tests all its products. The proportion of defective
items is 0.02. The probability that the test will catch a defective
product is 0.95. The test will also reject nondefective products
with probability 0.01. (a) Given that a product passes the test,
what is the probability that it is defective? (b) Given that the
product does not pass the test, what is the probability that the
product is defective?
85%
of the products are defective. Of the Next 15 products, what is the
probability that A) 3-6 are not defective. B) Fewer than 4 are not
defective C) More than 5 are not defective.
A manufacturing process produces 6.6% defective items. What is
the probability that in a sample of 40 items: a. 12% or more will
be defective? (Round the z-value to 2 decimal places and the final
answer to 4 decimal places.) Probability
b. less than 2% will be defective? (Round the z-value to 2
decimal places and the final answer to 4 decimal places.)
Probability
c) more than 12% or less than 2% will be defective? (Round the
z-value to 2...
There is a workshop of 20 people. During a section of the
workshop, the people are divided randomly into groups of 4. There
are six tables for six people.
Each group was randomly assigned to sit at one of the six
tables.
a) How many ways can four people be picked to be in the first
group formed?
b) After the first group is formed, how many ways can four
people be picked to be in the second group formed?...
It is known that 20% of products on a production line are
defective. a. Randomly pick 5 products. What is the probability
that exactly 2 are defective? b. Products are inspected until first
defective is encountered. Let X = number of inspections to obtain
first defective. What is the probability that X=5?
A box contains 10 items, of which 3 are defective and 7 are
non-defective. Two items are randomly selected, one at a time, with
replacement, and x is the number of defective items in the sample.
To look up the probability of a defective item being drawn from the
box, using a binomial probability table, what would be the values
of n, x and p to look up?
Suppose the probability that the probability of rain today in
Vernon is 0.4 and the probability of rain today in Kelowna is 0.3.
The probability that it will rain in both cities today is 0.2. A)
What is the probability that it will rain in Kelowna or Vernon
today? B) What is the probability that it will rain Kelowna today
but not in Vernon? C) Suppose that it has started to rain in
Kelowna today. What is the conditional probability...
QUESTION 23 Probability of Defective Products A
bottling machine is designed to fill 16.75 fluid ounces of water in
each water bottle. However, the actual fillings vary by small
quantities. For many reasons, either too much water or too little
water per filling is not desirable. Thus, the quality assurance
manager puts out the following specification limits for the water
content of each bottle: an LSL of 16.63 fluid ounces and a USL of
16.87 fluid ounces. Based on a very...
With probability 0.6, the present was hidden by mom; with
probability 0.4, it was hidden by dad. When mom hides the present,
she hides it upstairs 70 percent of the time and downstairs 30
percent of the time. Dad is equally likely to hide it upstairs or
downstairs. Given that it is downstairs, what is the probability it
was hidden by dad?
