Ashlynn performed an experiment in which she randomly drew one marble at a time from a bag. She recorded her results and returned the marble to the bag
The bag contained one marble each of the foloowing color: red, blue, green, yelow, and purple. The results of her experiment are shown below.
Times Drawn
13
Marble color
red. 8
blue. 13
green. 10
yellow.6
purple.11

Based on the experiment above, predict the number of times a green marble would be drawn if Ashlynn performs the experiment a total of 144 times.
A. 39
B. 30
C. 48
D. 24

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?
