Question

As you eat your way through a bag of chocolate chip cookies, you observe that each cookie is a circular disk with a diameter of 8.50

Answer #1

consider the cookie to be cylinder of volume pi*(t+
u1)((r+u2)^2)

t = thickness

r = radius (.5 diametre)

u1 = measured deviation from standard radius

u2 = measured deviation from standard thickness

m1 = maximum uncertainty of radius

m2 = maximum uncertainty of thickness

the average volume of the cookie for independent errors is

pi*average r * average r * average thickness

the uncertainty is largest cookie - smallest cookie

pi*(t+ m1)((r+m2)^2) - pi*(t - m1)((r-m2)^2)

b)

(2r+u2)/(t+u1)

uncertainty is largest numerator/smallest denominator - smallest
numerator/largest denominator

(2r+m2)/(t-m1) - (2r-m2)/(t+m1)

substitute appropriate values and calculate

Casey buys a bag of cookies that contains 6 chocolate chip
cookies, 5 peanut butter cookies, 5 sugar cookies and 7 oatmeal
raisin cookies. What is the probability that Casey randomly selects
a chocolate chip cookie from the bag, eats it, then randomly
selects another chocolate chip cookie?

Austin buys a bag of cookies that contains 4 chocolate chip
cookies, 6 peanut butter cookies, 6 sugar cookies and 8 oatmeal
cookies.
What is the probability that Austin reaches in the bag and randomly
selects a chocolate chip cookie from the bag, eats it, then reaches
back in the bag and randomly selects a peanut butter cookie?
Give your answer as a fraction, or accurate to at least 4
decimal places.

Kianna buys a bag of cookies that contains 19 chocolate chip
cookies, 12 sugar cookies, 9 peanut butter cookies and 2 oatmeal
cookies. What is the probability that Kianna reaches in the bag and
randomly selects a peanut butter cookie from the bag, eats it, then
reaches back in the bag and randomly selects an oatmeal
cookie?
Round your answer to 4 decimal places.
