There are 109,453,344 different LOTTO selections.
Solución
It seems there was an error in the calculation. Let's simplify the expression manually:
\[ C(68, 6) = \frac{68!}{6! \times 62!} \]
Now, we can calculate the number of different selections possible in LOTTO.
Simplify the expression by following steps:
- step0: Solution:
\(\frac{68!}{\left(6!\times 62!\right)}\)
- step1: Remove the parentheses:
\(\frac{68!}{6!\times 62!}\)
- step2: Expand the expression:
\(\frac{68\times 67\times 66\times 65\times 64\times 63\times 62!}{6!\times 62!}\)
- step3: Reduce the fraction:
\(\frac{68\times 67\times 66\times 65\times 64\times 63}{6!}\)
- step4: Multiply the terms:
\(\frac{78806407680}{6!}\)
- step5: Calculate the value:
\(\frac{78806407680}{720}\)
- step6: Reduce the fraction:
\(109453344\)
The number of different selections possible in LOTTO is \( 1.094533 \times 10^8 \) or \( 109,453,344 \).
Therefore, there are \( 109,453,344 \) different LOTTO selections.

To find the number of different selections possible when choosing 6 numbers from a collection of 68, you can use the combination formula, which is given by: \[ C(n, k) = \frac{n!}{k!(n-k)!} \] In this case, \( n = 68 \) and \( k = 6 \). Plugging in the values, we get: \[ C(68, 6) = \frac{68!}{6!(68-6)!} = \frac{68!}{6! \cdot 62!} = \frac{68 \times 67 \times 66 \times 65 \times 64 \times 63}{6 \times 5 \times 4 \times 3 \times 2 \times 1} = 11238513 \] So, there are **11,238,513** different LOTTO selections possible.
