If I sum a binomial random variable with n=5 and p =0.3 and a binomial random variable with m=10 and p =0.5, I get
Select one:
a. Something unfamiliar to us as yet
b. A normal distribution
c. A binomial random variable with number of Bernoulli trials =15 and p =0.4
d. A Binomial with number of Bernoulli trials =15 and p=0.4
a. Something unfamiliar to us as yet
The binomial distributions add to for another binomial distribution if the probability of success, p is same for both distributions that are to be added. here, p is different for the two binomial random variables and hence it forms some discrete distribution which cannot be classified as any of the option given here.

1. Imagine a coin toss experiment, where P(Heads)-P(Tails) 0.5. Define a random variable of your choice for this experiment and come up formulation for a question about this experiment, so that The distribution of a random variable for this experiment follows a binomial distribution The distribution of a random variable for this experiment follows a geometric distribution a. b. Note: you are only required to come up with the problem statement. Note, that this experiment itself is a Bernoulli trial....
4. Consider a binomial random variable with n = 5 and p = 0.7. Let x be the number of successes in the sample. Evaluate the probability. (Round your answer to three decimal places.) 5. Let x be a binomial random variable with n = 8, p = 0.2. Find the following value. 6. Let x be a binomial random variable with n = 8, p = 0.3. Find the following value. (Round your answer to three decimal places.)
Show that if X follows a binomial distribution with n, trials and probability of success p,-p,jz 1,2, Hint: Use the moment generating function of Bernoulli random variable) 1. , n and X, are independent then X, follows a binomial distribution.
5. A random variable X follows a binomial distribution with n 35 and p-4. Use the normal approximation to the binomial distribution to find P(X < 16)
Let X be a binomial random variable with n = 150 and p = 0.4. Use the normal approximation to find the following. Do not solve this as a binomial distribution problem. You must set up and use the normal approximation to receive credit. Express the final answer using 4 decimal places. a) P(48 ≤ X ≤ 66) b) P(X > 69)
Let X be a binomial random variable with p 0.3 and n 10. Calculate the following probabilities from the binomial probability mass function. Round your answers to four decimal places (e.g. 98.7654). P(X> 8)
1. For a given binomial distribution with n fixed trials and p, which is the probability of success of each trial, the binomial distribution is skewed left if p=0.50 Select one: True or False 2. Consider a graph of a normal distribution with the mean μμ and standard deviation σσ. The graph will never cross the horizontal axis. This happens because the normal distribution is an exponential function. Select one: True or False 3. Suppose you flip a fair a...
