Can someone help me to solve it by Matlab? Use the Boffon's Needle experiment to approximate pi on the following scenario. A dart is thrown at a square with sidelength 2. A circle is inscribe within the square. First deduce what the probability of the dart landing inside or on the edge of the circle is. Now write a Matlab script which approximates by simulating many dart throws. Run your script when n-10000, 100000, 1000000, 10000000, and 100000000 times, and...

Can someone help me to solve it by Matlab? ) Many dice games use two 6-sided dice, where each side faces up with equal probability, each turn consists of rolling both dice, and where the SUM of the two dice values is the outcome used in the game. Figure out how to simulate 3600 such die rolls, and then to make a nicely designed histogram displaying the outcomes as a PERCENT of the total rolls
