Object 1: Pop Tart Box - 3D shape: rectangular prism - Height 6.5in. - Base 4.5in. by 3.5in. Object 2: Potato Soup Can – 3D shape: Cylinder – Height 4.5in. – Circumference 3.5in.
Base of Object 1 : - 4 ½ in x 3 ½ - Formula for Area: Area = B * H - Base Area: 4 ½ x 3 ½ = 15.75 in^2
Base of Object 2: 3.5 - Formula for Area: 2pi x r^2 - Base Area: 1.75^2 x 2pi (using 3.14)= 19.2325

Find volume and surface area of both objects.

In a test for esp (extrasensory perception), a subject is told that cards only the experimenter can see contain either a star, a circle, a wave, or a square. as the experimenter looks at each of 20 cards in turn, the subject names the shape on the card. a subject who is just guessing has probability 0.25 of guessing correctly on each card. a. the count of correct guesses in 20 cards has a binomial distribution. what are n and p? b. what is the mean number of correct guesses in 20 cards for subjects who are just guessing? c. what is the probability of exactly 5 correct guesses in 20 cards if a subject is just guessing?

George writes the mixed number as sum and uses the distributive property 1/2.-2/5=1/2-2+2/5=1/2

Suppose you have 10 skittles. 5 green and 5 red. you choose 4 without looking. what is the probability that all 4 skittles will be green?
