Math Problem Statement

In the above scenario, when there were 53 numbers to choose from, and players pick 6 numbers. The calculations for this are shown step by step in the above image using the Combination formula. Use the information above to answer the following questions:

What are the odds of winning in this scenario with one winning ticket?

Solution

To find the odds of winning when there are 53 numbers to choose from and players pick 6 numbers, we need to calculate the total number of possible combinations and then find the probability of picking the winning combination.

Step 1: Calculate the Total Number of Combinations

The number of ways to choose 6 numbers out of 53 without regard to the order is given by the combination formula:

C(n,k)=n!k!(nk)!\text{C}(n, k) = \frac{n!}{k!(n-k)!}

where:

  • nn is the total number of items (53 in this case),
  • kk is the number of items to choose (6 in this case).

Substituting the values, we get:

C(53,6)=53!6!(536)!=53!6!×47!\text{C}(53, 6) = \frac{53!}{6!(53-6)!} = \frac{53!}{6! \times 47!}

Calculating this:

  1. 53!=53×52×51×50×49×48×47!53! = 53 \times 52 \times 51 \times 50 \times 49 \times 48 \times 47!
  2. 6!=6×5×4×3×2×1=7206! = 6 \times 5 \times 4 \times 3 \times 2 \times 1 = 720
  3. 47!47! cancels out in the numerator and the denominator.

Thus, we have:

C(53,6)=53×52×51×50×49×48720\text{C}(53, 6) = \frac{53 \times 52 \times 51 \times 50 \times 49 \times 48}{720}

C(53,6)=22,957,48072031,573,815\text{C}(53, 6) = \frac{22,957,480}{720} \approx 31,573,815

Step 2: Calculate the Probability of Winning

The probability of winning is the ratio of the number of winning outcomes (1) to the total number of possible outcomes:

Probability of Winning=131,573,815\text{Probability of Winning} = \frac{1}{31,573,815}

Step 3: Express the Odds

The odds of winning can be expressed as:

Odds of Winning=131,573,815\text{Odds of Winning} = \frac{1}{31,573,815}

This means that there is 1 chance of winning in 31,573,815.
