Probability and Statistics
Consider the following experiment. You draw a square, of width 1 foot, on the floor. Inside the square, you inscribe a circle of diameter 1 foot. The circle will just fit inside the square. You then throw a dart at the square in such a way that it is equally likely to fall on any point of the square. What is the probability that the dart falls inside the circle? (Think about area!)How might this process be used to estimate the value of π?
Problem 1.
You are playing a version of the roulette game, where the pockets are
from 0 to 10and even numbers are red and odd numbers are black (0 is
green). You spin 3 times and add up the values you see. What is the
probability th at you get a total of 17 given on the first spin you
spin a 2? What about a 3?
Solve by simulation and analytically.
There are 7 balls hidden in a box (3 blue and 4 green). If you first select a green ball and do not replace in the box, what is the probability that the second ball you select from the box will also be green? [Your answer can be written either as a fraction or decimal]

- Three coins are tossed at the same time, each equally likely to come up heads or tails. What is the probability of getting 1 head and 2 tails?arrow_forwardSuppose you have two boxes A and B. Box A contains 7 black marbles, 4 white marbles. Box B contains 7 white and 4 black marbles. A random experiment is performed in two sequential trials by first drawing a marble randomly from box A and putting into Box B. In the second trial after the first trial, a marble is drawn randomly from box B. If we reverse the scenario, then what is the probability of drawing a black marble from box A given that a white marble is drawn from box B.arrow_forwardSize of sample space A six-sided dice is rolled, a five-sided dice is rolled and a three-sided dice is rolled.

- A coin is flipped 10 times in a row. a. What is the probability that it lands heads up exactly 8 times? b. What is the probability that it lands heads up at least 8 times? c. What is the probability that it lands heads up at most 8 timesarrow_forward6. AND Since there are two zeros on the board, let's determine the probability that you would be able to cover them on 2 consecutive turns. This means you'd have to roll a zero and then roll another zero. You can think of this as an AND probability. You need to roll 0 AND then you need to roll 0 again. Since the result of the first roll will have no influence on the result of the second roll, you can use the following rule: P(A and B) = P(A) * P(B) a) Determine P(0 and 0). b) Determine 1 - P(0 and 0). c) Write a sentence describing the meaning of 1 - P( Oand 0 ).arrow_forwardOne side of a coin is selected at random ten times, and each time it's either heads or tails. Is there a limit on the number of outcomes that can have less than four possible outcomes?arrow_forward
- Correct answer will be upvoted else Multiple Downvoted. Computer science. You are approached to watch your nephew who likes to play with toy blocks unusually. He has n boxes and the I-th box has simulated intelligence blocks. His game comprises of two stages: he picks a subjective box I; he attempts to move all squares from the I-th box to other boxes. If he can make similar number of squares in each of n−1 other boxes then he will be cheerful, any other way, will be tragic. Note that your nephew can just move the squares from the picked box to the next boxes; he can't move blocks from the other boxes. You would rather not make your nephew dismal, so you chose to place a few additional squares into some containers so that regardless of which box I he picks he will not be pitiful. What is the base number of additional squares you want to put? Input The main line contains a solitary integer t (1≤t≤1000) — the number of experiments.

(a) What is the probability that a randomly selected coin from the box will come up heads when flipped? (b) Suppose you randomly pick a coin from the box and flip it, and it comes up heads. What is the probability that it's one of the trick coins? (c) Let X be the random variable that represents the number of heads when every coin in the box is flipped. What is the probability distribution of X? (Hint: you can try counting all the outcomes, or you can remember that coin flips are independent of each other.)
