Suppose you again have seven coins in your pocket, 1 quarter, 4 dimes, and 2 pennies. Again, you randomly extract one coin from your pocket, look at the coin, and then return that coin to your pocket. You then randomly extract a second coin from your pocket and look at that coin. If the events are again P1 = "first pick was a penny" and D2 = "Second pick was a dime," what is the probability of picking these two...
You have seven coins in your pocket, 1 quarter, 4 dimes and 2 pennies. Assume you randomly extract one coin from your pocket, and without replacing it you pick a second coin. If the events are P1 = “first pick was a penny” and D2 = “second pick was a dime,” what is the probability of picking these two coins? Show how you arrived at your conclusion (using probabilities).
2. Write a JAVA program that prints the numbe r of quarters, dimes, nickels, and pennies that a customer should get back as change. Declare and initialize all memory locations as integers. On Output show the original change amount as a monetary amount with the two positions of decimal. Run your program once by performing a compile-time initializations using 92 cents for the calue to be converted. Go into your source code and change the 92 to 27. Return the...
show work for each part 3. Suppose a bag contains 2 quarters, 1 dime, 5 nickels, and 3 pennies. a. If you randomly select one coin out of the bag, what is the probability that it is a nickel? P(N)= b. If you randomly select one coin out of the bag, what is the probability it is not a quarter? P@= c. If you select two coins with replacement, what is the probability of picking a dime (D1) and then...
Your program must meet the following specifications: 1. At program start, assume a stock of 10 nickels, 10 dimes, 10 quarters, and 10 pennies. 2. Repeatedly prompt the user for a price in the form xX.xx, where X denotes a digit, or to enter q' to quit 3. When a price is entered a. If the price entered is negative, print an error message and start over requesting either a new price or to quit (indicated by entering a 'q)...
A fast food manager wants to be prepared to have enough of COIN change (pennies, nickels, dimes, and quarters) at the drive through window ready to give to customers. Let X be the amount of COIN change that any customer is given back when they pay for their food at the drive-up window (in decimal form.) Suppose f(x) is as given below. f(x) = kx(1-x) where 0 ≤ x < 1.00 and k is some constant > 0 Find...
