For each Bernoulli process, find the expected number of successes: 1. Number of trials =10, Probability of success =0.6 2. Number of trials =210, Probability of success =1/10. 3. Number of trials =43, Probability of success =0.3. 4. Number of trials =23, Probability of failure =0.8. 5. Number of trials =59, Probability of failure =2/7.
2. Suppose 4 Bernoulli trials, each with success probability p, are con ducted such that the outcomes of the 4 experiments pendent. Let the random variable X be the total number of successes over the 4 Bernoulli trials are mutually inde- (a) Write down the sample space for the experiment consisting of 4 Bernoulli trials (the sample space is all possible sequences of length 4 of successes and failures you may use the symbols S and F). (b) Give the...
Negative Binomial experiment is based on sequences of Bernoulli trials with probability of success p. Let x+m be the number of trials to achieve m successes, and then x has a negative binomial distribution. In summary, negative binomial distribution has the following properties Each trial can result in just two possible outcomes. One is called a success and the other is called a failure. The trials are independent The probability of success, denoted by p, is the...
1. Given that x has a Poisson distribution with μ=4, what is the probability that x=6? Round to four decimals. 2. Assume the Poisson distribution applies. Use the given mean to find the indicated probability. Find P(4) when μ=7. Round to the nearest thousandth. 3. Given that x has a Poisson distribution with μ=0.4, what is the probability that x=4? Round to the nearest thousandth. 4. Describe the difference between the value of x in a binomial distribution and in...
Problem 1 Consider a sequence of n+m independent Bernoulli trials with probability of success p in each trial. Let N be the number of successes in the first n trials and let M be the number of successes in the remaining m trials. (a) Find the joint PMF of N and M, and the marginal PMFs of N and AM (b) Find the PMF for the total number of successes in the n +m trials. Problem 1 Consider a sequence...
