1/365 = 0.00274
The probability is approx 0.81
The probability is 10 percent.
It depends on what the random variable is, what its domain is, what its probability distribution function is. The probability that a randomly selected random variable has a value between 40 and 60 is probably quite close to zero.
probability = 2/7 to be exact, 28/97 (about 28.87%)
1. a) A box of 30 diodes is known to contain five defective ones. If two diodes are selected at random without replacement, what is the probability that atleast one of these diodes is defective
random sample
When each member of the population has the same probability of being selected as a member of the sample.
Using the hypergeometric distribution, the answer is 2114/3003 = 0.7040
It is a simple random sample.
This is called a random sample.
