- In a certain lottery, an urn contains balls numbered 1 to 37. From this urn, 5 balls are chosen randomly, without replacement. For a $1 bet, a player chooses one set of five numbers. To win, all five numbers must match those chosen from the urn. The order in which the balls are selected does not matter. What is the probability of winning this lottery with one ticket? The probability of winning is (Use scientific notation. Use the multiplication symbol in the math palette as needed. Round to the nearest hundredth as needed.).When purchasing a ticket for the PowerBall lottery game a player chooses 5 distinct numbers between 1 and 69 (inclusive). The order in which the numbers are chosen does not matter. In addition, the player chooses one number between 1 and 26 (inclusive) to match the "powerball." How many different powerball tickets are possible?Asap
