Math Problem Statement

In a lottery game, a player picks 6 numbers from 1 to 47. If 5 of the 6 numbers match those drawn, the player wins second prize. What is the probability of winning this prize? Be sure to leave your answer as a fraction in order to earn credit.

There is a 24610737573​Incorrect probability of winning second prize.

Hint: The chances of winning are the total ways you can pick 5 out of 6 numbers divided by the number of ways you can pick 6 numbers out of 47.

Solution

To calculate the probability of winning second prize in the lottery, we need to determine two things:

  1. The number of ways the player can match 5 out of the 6 numbers they chose.
  2. The total number of ways 6 numbers can be chosen out of the 47 possible numbers.

Step 1: Total number of possible combinations

The total number of ways to choose 6 numbers out of 47 is calculated using the combination formula:

(nk)=n!k!(nk)!\binom{n}{k} = \frac{n!}{k!(n-k)!}

Where:

  • n=47n = 47 (total numbers available),
  • k=6k = 6 (numbers chosen).

This gives us the total number of ways to choose 6 numbers from 47.

Step 2: Favorable outcomes (matching 5 of 6 numbers)

For the second prize, the player must match 5 out of the 6 chosen numbers. The player can:

  • Choose 5 numbers from the 6 correct numbers, and
  • Choose 1 number from the 41 remaining numbers (since 6 numbers are drawn, the remaining 41 numbers are incorrect).

So, we need to calculate:

  • (65)\binom{6}{5} for selecting 5 correct numbers,
  • (411)\binom{41}{1} for selecting 1 incorrect number.

Step 3: Probability formula

The probability is given by:

P(second prize)=(65)×(411)(476)P(\text{second prize}) = \frac{\binom{6}{5} \times \binom{41}{1}}{\binom{47}{6}}

Let me calculate this.It seems like I can’t do more advanced data analysis right now. Please try again later.

However, I can guide you on how to calculate the probability manually:

  1. Total combinations of choosing 6 numbers from 47: (476)=47!6!(476)!\binom{47}{6} = \frac{47!}{6!(47-6)!}

  2. Favorable outcomes: Choose 5 correct numbers from 6 and 1 incorrect from 41: (65)×(411)\binom{6}{5} \times \binom{41}{1}

Finally, the probability is the ratio of favorable outcomes to total combinations: P=(65)×(411)(476)P = \frac{\binom{6}{5} \times \binom{41}{1}}{\binom{47}{6}}
