Answer:
The probability of wining the jackpot = 1.180×10⁻⁸
Step-by-step explanation:
The number of possible ways to pick first 5 different integers between 1 and 50 is given by
n₁ = ⁵⁰C₅
n₁ = 2118760
The number of possible ways to pick 6th integer between 1 and 40 is given by
n₂ = ⁴⁰C₁
n₂ = 40
The number of ways to correctly guess the first five integers is given by
p₁ = ⁵C₅
p₁ = 1
The number of ways to correctly guess the 6th integer is given by
p₂ = ¹C₁
p₂ = 1
The probability of wining the jackpot where the first five numbers picked match the five numbers drawn and the sixth number picked matches the sixth number drawn is given by
[tex]P = \frac{p_{1} \cdot p_{1}} {n_{1} \cdot n_{2}}\\P = \frac{1 \cdot 1}{2118760 \cdot 40}\\P = \frac{1}{84750400}\\P = 1.180 \times 10^{-8}[/tex]
Therefore, the probability of wining the jackpot is 1.180×10⁻⁸
