Final answer:
To win the grand jackpot in the You-Pick-4 lottery game, you must match all 4 numbers in the correct order. The probability of winning the grand jackpot with one ticket is 1/707,281.
Step-by-step explanation:
To win the grand jackpot in the You-Pick-4 lottery game, you must match all 4 numbers in the correct order. Since there are 29 numbers to choose from, the probability of choosing the correct first number is 1/29. Similarly, the probability of choosing the correct second number, third number, and fourth number are also 1/29 each. To find the probability of winning the grand jackpot, we multiply these probabilities together: 1/29 * 1/29 * 1/29 * 1/29 = 1/707,281.
Therefore, the probability of winning the grand jackpot with one ticket is 1/707,281. So, the correct answer is b. 1/707,281.
