A pizza store has 300 pizza capacity per day and it is usually working at full capacity(assume a binomial probability distribution.......

n=300 x=280 p=7/100=0.07
q=1-p=1-0.07=0.93
P(X=x)=ncx px qn-x
p(x<280)=1-{p(x=280)+p(x=281)+p(x=282)+p(x=283)+......+p(x=300)
Pull all these values then calculated the ans.
We are interested in determining the probability that a retail store will meet its daily revenue goal of $100. Analysis of sales history indicates that daily demand, D is random and independent of the demand on other days. Assume D follows the distribution below P(D=d) = 0.3, d=0 0.3, d=1 0.2, d=2 0.1, d=3 0.1, d=4 Furthermore, due to a complicated discount structure, the shop has determined that their revenue per day can be modeled as R(s) = −100 cos(20s)...
A popular resort hotel has 300 rooms and is usually fully booked. About 5% of the time a reservation is canceled before the 6 p.m. deadline with no penalty. What is the probability that at least 282 rooms will be occupied? Use the binomial distribution to find the exact value?
Historical data show that customers who download music from a popular Web service spend approximately $24 per month, with a standard deviation of $3. Assume the spending follows the normal probability distribution. Find the probability that a customer will spend at least $21 per month. How much (or more) do the top 7% of customers spend? What is the probability that a customer will spend at least 521 per month? (Round to four decimal places as needed.) How much do...
Daily demands for loaves of bread at a grocery store are specified by following probability distribution: the store buys a loaf for 55 cents and sell it for $1.20 each. any unsold loaves at the end of the day are disposed of at 25 cents each. assume that the stock level is restricted to one of the demand levels specified for Pn. n 100 150 200 250 300 Pn 0.20 0.25 0.30 0.15 0.10 1) Develop the associated decision tree....
3. Binomial Random Variable: On your way home from work at 9pm every day You estimate that 25% of the time, they have at least one slice of pepperoni pizza (your favorite) from work at 9pm every day, you pass your favorite pizza store. remaining, 75% of the time, they have already sold out of slices. Assume that whenever there is pizza available, you will buy one slice. Consider the last 10 days and let X represent the number of...
You may need to use the appropriate appendix table or technology to answer this question. Assume a binomial probability distribution has p = 0.70 and n = 300. a.What is the probability of 190 to 200 successes? Use the normal approximation of the binomial distribution to answer this question. (Round your answer to four decimal places.) b.What is the probability of 220 or more successes? Use the normal approximation of the binomial distribution to answer this question. (Round your answer...
Assume each newborn baby has a probability of approximately 0.51 of being female and 0.49 of being male. For a family with three children, let Xequalsnumber of children who are girls. a. Identify the three conditions that must be satisfied for X to have the binomial distribution. b. Identify n and p for the binomial distribution. c. Find the probability that the family has one girl and two boys.
3. A factory produces screws in batches of 100,000. The probability that a screw is defective is 0.01%. Assume that defects occur independently of each other. (a) Approximate the probability that 15 or more screws in a batch are defective using the normal approximation to the binomial distribution. (b) Approximate the probability that 3 or fewer screws in a batch are defective using the normal approximation to the binomial distribution. (c) Approximate the probability that 3 or fewer screws in...
