A binomial distribution describes the possible number of times that a particular event will occur in a sequence of observations.
• A trial has only two possible outcomes namely success or failure.
• There is fixed number of identical trials.
• The trials of the experiment are independent of each other.
The probability mass function of Binomial distribution is,
Here,
The number of trials
The probability of success
The probability of failure
From the given information we have,
Sample size
Probability of success is
Let X be the number of defective keyboards. Here
The probability mass function is given by,
Compute the probability that none of the keyboards are defective. That is,
Ans:The probability that none of the keyboards are defective is 0.7351.

Judging from recent experience, 4% of the computer keyboards produced by an automatic, high-speed machine are defective. If 10 keyboards are randomly selected, what is the probability that exactly 1 of the keyboards are defective? O 942 665 O 052
An automatic spot-welding machine is used in an assembly plant. It is known that 5 percent of the welds made by the machine are defective. If 10 welds made by the machine are in spected at random, what is the probability of finding (a) no defective welds, (b) exactly one defective weld, (c) at least one defective weld, and (d) no more than one defective weld?
apter 1. Consider the following data on distances traveled by 100 people to visit the local park. 1-8 30 25 20 15 10 9-16 17-24 25-32 33-40 Expand and construct the table adding columns for relative frequency and cumulative relative frequency. Then plot Histogram, Frequency Polygon and Ogive Curve. 2. Math test anxiety can be found throughout the general population. A study of 200 seniors at a local high school was conducted. The following table was produced from the data....
SYNOPSIS The product manager for coffee development at Kraft Canada must decide whether to introduce the company's new line of single-serve coffee pods or to await results from the product's launch in the United States. Key strategic decisions include choosing the target market to focus on and determining the value proposition to emphasize. Important questions are also raised in regard to how the new product should be branded, the flavors to offer, whether Kraft should use traditional distribution channels or...
