Binomial Distribution Problem 1: (a) An urn contains 1000 balls, 100 are green and 900 are white. One ball is chosen from the ur
n 100 times with replacement. Use Excel (binom.dist) to find the probability that six or seven green balls are selected. (b) An urn contains 1000 balls, 100 are green and 900 are white. One ball is chosen from the urn 1000 times. Use Excel (binom.dist) to find the probability that between 110 and 120 of the balls, inclusive, are green. (c) Redo (a) and (b) again using Excel but use the normal approximation (normal.dist). How do the answers compare with the above? Are there any discrepancies? If so, please explain why they happened. Please submit your answers on an excel spreadsheet.

Answer:
Step-by-step explanation:
Since we know that you write 17 text messages a week. 17 will be our constant number, now then after you said for x weeks.
Meaning that x would be our variable cause we can put an input of any number, then put it next to 17 because that is how many times you text a week.
17x = y
17 (how many times you text per week) x (how many weeks) = y (texts in total)
