Let X1, X2, X3, X4 be random variables that are all independent of each other and have the same distribution, namely, P(X1 = 1) = 0.2, P(X1 = 0) = 0.8, and identically so for X2, X3, X4. Calculate the probability that P(X1 + X2 + X3 + X4 <= 3)

Suppose the time it takes my daugther, Lizzie, to eat an apple is uniformly distributed between 6 and 10 minutes. Let X = the time, in minutes, it takes Lizzie to eat an apple. What is the probability that it takes Lizzie more than 11 minutes to finish the next apple? What is the probability that it takes Lizzie at least 7.2 minutes to finish the next apple? What is the probability that it takes Lizzie fewer than 6.3 minutes or more than 8 minutes to finish the next apple?
Based on the survey assume that 49% of consumers are comfortable having drones deliver their purchases. Suppose that we want to find the probability that 5 consumers are randomly selected exactly 2 of them are comfortable with delivery by drones. Indemnify values of n, x, p, and q.
Two random variables X and Y are independent. Each has a binomial distribution with success probability 0.4 and 2 trials. a) Find the joint probability distribution function f(x,y). b) Give the joint probabilities using a table. Hint, the size of the table is 3 by 3. c) Find the probability P(Y > X).
In a digital communication channel, assume that the number of bits received in error can be modeled by a binomial random variable, and assume that the probability that a bit is received in error is 0.0001. If 150,000 bits are transmitted, what is the probability that errors are between 10 and 18? How to compute P(X=10)= (150000c10)(0.0001)10(1-0.0001)150000-10
A delivery truck travels from point A to point B and back using the same route each day. There are four traffic lights on the route. Let X1 denote the number of red lights the truck encounters going from A to B and X2 denote the number encountered on the return trip. Data collected over a long period suggest that the joint probability distribution for (X1, X2) is given by Please show complete solution.
According to recent reports, currently 39% of the population of NC (adults and children) has been fully vaccinated against Covid. Suppose of random sample of 400 individuals from the population of NC is selected. Let x represent the number in the sample who are fully vaccinated. d. Find the probability that 130 or fewer in the sample have been fully vaccinated. Round to 4 decimal places. Would this result be unusual? Explain.
