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 41​) 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

In this lottery, the player wins the jackpot by matching:

  • Five distinct numbers drawn from the 41 white balls, and
  • One number drawn from the 34 gold balls.

To calculate the probability of winning, we need to find the total number of possible outcomes (the sample space) and the number of favorable outcomes (the winning outcome).

Step 1: Total number of possible outcomes

  • White balls: The player needs to choose 5 distinct numbers from a set of 41 white balls. Since the order of selection doesn't matter, this is a combination problem. The number of ways to choose 5 numbers from 41 is given by the combination formula: (415)=41!5!(415)!\binom{41}{5} = \frac{41!}{5!(41 - 5)!}

  • Gold ball: There are 34 possible outcomes for the gold ball (the number drawn from 1 to 34).

Thus, the total number of possible outcomes is: Total outcomes=(415)×34\text{Total outcomes} = \binom{41}{5} \times 34

Step 2: Number of favorable outcomes

There is only one favorable outcome, where the player matches all 5 white balls and the correct gold ball.

Step 3: Probability of winning

The probability PP of winning is the ratio of favorable outcomes to total outcomes: P=1(415)×34P = \frac{1}{\binom{41}{5} \times 34}

Now, let's calculate the values:

  • First, calculate (415)\binom{41}{5}: (415)=41×40×39×38×375×4×3×2×1=4,496,388\binom{41}{5} = \frac{41 \times 40 \times 39 \times 38 \times 37}{5 \times 4 \times 3 \times 2 \times 1} = 4,496,388

  • Now, calculate the total number of outcomes: Total outcomes=4,496,388×34=152,780,232\text{Total outcomes} = 4,496,388 \times 34 = 152,780,232

  • Therefore, the probability of winning the jackpot is: P=1152,780,232P = \frac{1}{152,780,232}

Final Answer:

The probability of winning the jackpot is approximately: P6.55×109P \approx 6.55 \times 10^{-9} which is a very small probability.
