Coin box Question: Assume that there are 25 pennies, 10 nickels, 10 dimes, and 5 quarters in a box. after shuffeling the box, you pick a coin at random and note down its face value. let x represent the face value of the coin in cents. then construct the probability distribution of x. The question I need to find is...Find P(x is at most 12) ? I am not sure what to do or how to do it. i would appreciate the help. Thanks,
You have a probability of getting a penny is 25/50
prob nickel is 10/50
prob of dime is 10/50
prob quarter is 5/50
