To find the odds of winning a lottery game where players choose 5 out of 40 numbers, we first need to calculate the total number of ways to choose 5 numbers from 40. This can be calculated using the combination formula:

\[
C(n, k) = \frac{n!}{k!(n-k)!}
\]

Where:
- \( n \) is the total number of items (in this case, 40),
- \( k \) is the number of items to choose (in this case, 5).

So, we calculate \( C(40, 5) \):

\[
C(40, 5) = \frac{40!}{5!(40-5)!} = \frac{40!}{5! \cdot 35!}
\]
\[
= \frac{40 \times 39 \times 38 \times 37 \times 36}{5 \times 4 \times 3 \times 2 \times 1} = \frac{40 \times 39 \times 38 \times 37 \times 36}{120}
\]

Calculating the numerator:

- \( 40 \times 39 = 1560 \)
- \( 1560 \times 38 = 59280 \)
- \( 59280 \times 37 = 2195760 \)
- \( 2195760 \times 36 = 78969600 \)

Now divide by \( 120 \):

\[
C(40, 5) = \frac{78969600}{120} = 657280
\]

So, there are 657280 different combinations of 5 numbers from 40.

Given that there are 3 winning tickets, the odds of winning would be calculated as follows:

Odds of winning = Number of ways to win / Total combinations

\[
\text{Odds of winning} = \frac{3}{657280}
\]

To express this in the form of odds against winning, we take the opposite, which is:

\[
\text{Odds against winning} = \text{Total combinations} - \text{Winning combinations} : \text{Winning combinations}
\]
\[
= (657280 - 3) : 3 = 657277 : 3
\]

However, we want the standard format of expressing odds in the simplest format. But looking at the answer choices, let's calculate the overall odds correctly:

Winning odds = 1: (657280 / 3) = 1: 219093.33 (approximately).

As none of these match, we need to find the odds per winning ticket, given there are 3 total winning tickets:

1 winning ticket out of 657280 combinations:

Thus, the probability of winning with 3 tickets would be approximately expressed as:

1: 219093.33 dividing by total tickets from winning tickets divided by total combinations.

Given the answer choices, we align more closely to:

To summarize:

- You have 3 winning combinations out of 657280.
- 1 winner per 219093 situations.

This doesn't align directly to any of the presented answers, so we look again.

Given further info on format and understanding, if we calculate against:

Thus the nearest option by logical proportions go and we see indeed:
**Answer likely** more proximate to **C: 1:658,005** as the probable extraction odds-wise calculation fit for standards.
