Using the formula (page 166, noting that n Or = ), this website , Excel or another tool of your choice, or RStudio (codes found on page 166), find the probability that none are left-handed, rounded to 4 decimal places. Hint: sketch a histogram with the numbers 0 through 15 on the horizontal axis, counting the number of "lefties" in the group, with bars that are small for 0, medium for 1, big for 2, medium for 3, and decreasing in size for 4 through 15. The probability that the number of lefties in the group is equal to some number is exactly the area/height of its corresponding bar. The probability that the number of lefties in the group is less than some number is exactly the total areas/heights of the bars to its left. Similar conclusions can be drawn about "more than," "at least," and "at most."
