Explicação
## Step 1: Identify the possible payoffs### The possible payoffs for one ticket in the raffle are
,
.## Step 2: Determine the number of tickets for each payoff### There is 1 ticket that wins
, 17 tickets that win
0).## Step 3: Calculate the probabilities for each payoff### The probability \( P(X = x) \) is calculated by dividing the number of tickets with payoff
by the total number of tickets (250).- For
: \( P(X = 200) = \frac{1}{250} = 0.004 \)- For
: \( P(X = 90) = \frac{5}{250} = 0.02 \)- For
: \( P(X = 40) = \frac{17}{250} = 0.068 \)- For
: \( P(X = 0) = \frac{227}{250} = 0.908 \)## Step 4: Fill in the table with the calculated probabilities### Using the calculated probabilities, we can fill in the table as follows:
