Respuesta :
The probability that a six number combination selected is the winning combination [tex]\boxed{\frac{1}{{127512000}}}[/tex].
Further Explanation:
Probability can be defined as the ratio of favorable number of outcomes to the total number of outcomes.
Given:
There are [tex]25[/tex] numbers from one to twenty five
Concept used:
The probability [tex]P\left( E \right)[/tex] of any event [tex]E[/tex] can be calculated as,
[tex]P\left( E \right) = \dfrac{{n\left( E \right)}}{{n\left( S \right)}}[/tex]
Here, [tex]n\left( E \right)[/tex] is the total number of elements in event [tex]E[/tex] and [tex]n\left( S \right)[/tex] is the number of element in sample space of an experiment.
Calculation:
The probability that the first digit of lottery number is same as picked can be calculated as,
[tex]P\left( 1 \right) = \dfrac{1}{{25}}[/tex]
The probability that the second digit of lottery number is same as picked can be calculated as,
[tex]P\left( 2 \right) = \dfrac{1}{{24}}[/tex]
The probability that the third digit of lottery number is same as picked can be calculated as,
[tex]P\left( 3 \right) = \dfrac{1}{{23}}[/tex]
The probability that the fourth digit of lottery number is same as picked can be calculated as,
[tex]P\left( 4 \right) = \dfrac{1}{{22}}[/tex]
The probability that the fifth digit of lottery number is same as picked can be calculated as,
[tex]P\left( 5 \right) = \dfrac{1}{{21}}[/tex]
The probability that the sixth digit of lottery number is same as picked can be calculated as,
[tex]P\left( 6 \right) = \dfrac{1}{{20}}[/tex]
The probability that the all digit of lottery number is same as picked can be calculated as,
[tex]\begin{aligned}P &= \frac{1}{{25}} \times \frac{1}{{24}} \times \frac{1}{{23}} \times \frac{1}{{22}} \times \frac{1}{{21}} \times \frac{1}{{20}} \\ &= \frac{1}{{127512000}} \\ \end{gathered}[/tex]
The probability that a six number combination selected is the winning combination [tex]\boxed{\frac{1}{{127512000}}}[/tex].
Hence, [tex]\boxed{{\text{Option b}}}[/tex] is correct.
