Article about a lottery in which choosing a number involves combination:
“The lottery game “Megamillions” is played in over 40 states and requires $1 per ticket to play. To win the jackpot, one must correctly pick five unique numbers from balls numbered 1 through 56 (Order does not matter) and correctly pick the megaball number which is picked from the balls numbered 1 through 46. Thus probability of winning the jackpot remains almost less than ten millionth.”
To determine:
Probability of getting a matching number consisting of 6 numbers in which first 5 numbers we have to select out of 56 numbers and last number will be taken from another group of 46 numbers.

- Please help me organize the proof of the following theorem:arrow_forwardThe population mean and standard deviation are given below. Find the required probability and determine whether the given sample mean would be considered unusual. For a sample of n = 65, find the probability of a sample mean being greater than 225 if μ = 224 and σ = 3.5. For a sample of n = 65, the probability of a sample mean being greater than 225 if μ=224 and σ = 3.5 is 0.0102 (Round to four decimal places as needed.)arrow_forwarduestion 10 of 12 A Your answer is incorrect. L 0/1 E This problem concerns hybrid cars such as the Toyota Prius that are powered by a gas-engine, electric-motor combination, but can also function in Electric-Vehicle (EV) only mode. The figure below shows the velocity, v, of a 2010 Prius Plug-in Hybrid Prototype operating in normal hybrid mode and EV-only mode, respectively, while accelerating from a stoplight. 1 80 (mph) Normal hybrid- 40 EV-only t (sec) 5 15 25 Assume two identical cars, one running in normal hybrid mode and one running in EV-only mode, accelerate together in a straight path from a stoplight.
