Math Problem Statement

In one​ lottery, a player wins the jackpot by matching all five distinct numbers drawn in any order from the white balls​ (1 through 43​) and matching the number on the gold ball​ (1 through 34​). If one ticket is​ purchased, what is the probability of winning the​ jackpot?

Solution

To determine the probability of winning the jackpot in this lottery, we need to calculate two probabilities:

  1. The probability of correctly matching all five distinct numbers drawn from the white balls (1 through 43).
  2. The probability of correctly matching the number on the gold ball (1 through 34).

Step 1: Calculate the number of possible combinations of white balls.

  • The number of ways to choose 5 distinct numbers from 43 white balls is given by the combination formula:

(435)=43!5!(435)!=43!5!×38!\binom{43}{5} = \frac{43!}{5!(43-5)!} = \frac{43!}{5! \times 38!}

Calculating this:

(435)=43×42×41×40×395×4×3×2×1=962598\binom{43}{5} = \frac{43 \times 42 \times 41 \times 40 \times 39}{5 \times 4 \times 3 \times 2 \times 1} = 962598

So, there are 962,598 possible combinations of the white balls.

Step 2: Calculate the probability of matching the gold ball.

  • There are 34 possible numbers for the gold ball, so the probability of picking the correct one is:

134\frac{1}{34}

Step 3: Calculate the overall probability.

  • The probability of winning the jackpot is the product of the probability of matching all five white balls and the probability of matching the gold ball:

Probability of winning=1(435)×134=1962598×134\text{Probability of winning} = \frac{1}{\binom{43}{5}} \times \frac{1}{34} = \frac{1}{962598} \times \frac{1}{34}

Simplifying the product:

Probability of winning=1962598×34=132728332\text{Probability of winning} = \frac{1}{962598 \times 34} = \frac{1}{32728332}

Final Answer:

The probability of winning the jackpot with one ticket is:

132,728,332\frac{1}{32,728,332}
