Container 1 has 8 items, 3 of which are defective. Container 2
has 5 items, 2 of which are defective. If one item is drawn from
each container, what is the probability that only one of the items
is defective?

Box A contains 7 items of which 2 are defective, and box B contains 6 items of which 1 is defective. If an item is drawn at random from each box. Find the probability that both items are non- defective. 1/21 19/42 10/13 25/42
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?
A box of manufactured items contains 12 items of which 4 are
defective. If 3 items are drawn at random without replacement, what
is the probability that:
1. The first one is defective and rest are good
2. Exactly one of three is defective
Suppose that a bag contains 16 items of which 8 are defective.
Four items are selected at random without replacement. Find the
probabilities that:
Provide your answers in 2 d.p (decimal point) without space in
between the values
only one item is defective
all selected items are non-defective
all selected items are defective
at least one of the selected items is defective
A box contains 12 items of which 3 are defective. A sample of 3 items is selected from the box. Let X denotes the number of defective item in the sample. Find the probability distribution of X.
a. Suppose that 5 % of the items produced by a
factory are defective. If 5 items are chosen at random, what is the
probability that none of the items are defective? Write your answer
as a decimal accurate to three decimal places.
b. Suppose that 7.9 % of the items produced by a second factory
are defective. If 5 items are chosen at random from the second
factory, what is the probability that exactly one of the items is...
From a lot containing 25 items, 5 of which are defective, 4 are
chosen at random. Let X be the number of defective items found.
Obtain the probability distribution of X if (a) the items are
chosen with replacement, (b) the items are chosen without
replacement.
A production lot of 80 units has 8 defective items. We draw a random sample of 10 units and we want to know:
a.- the probability that the sample contains less than 3 defective articles
b.- the probability that the sample contains at least 3 good articles
c.- the probability that the sample contains more than 6 good articles
