. The teacher decides that no student can win twice, so she removes the tickets of the first winner before drawing the second wi
kozerog [31]

Answer:

<h2>There is 8% probability of Kitzen winning first and Ava second.</h2>

Step-by-step explanation:

The given table shows that there are 4 students, so there are 4 possible winner in total, but they have different number of tickets.

The total number of tickets is 48, that's the total possible outcomes. Kitzen has a probability of

P_{Kitzen}=\frac{12}{48}=\frac{1}{4}

Ava has a probability of

P_{Ava}=\frac{16}{48}=\frac{1}{3}

Now, the probability of having one event and the other is

P=\frac{1}{4} \times \frac{1}{3}=\frac{1}{12} \approx 0.08

Therefore, there is 8% probability of Kitzen winning first and Ava second.

(Notice that the probaility is not about Kitzen or Ava winning, it's about winning both, that's why the percentage is low)

Tell whether the statement is true or false. If w is 25% of Z, then Z:W is 75:25
melamori03 [73]
False.
If w is 25% of z, then w:z would be 25:100, because 25 is 25% of 100.
If Z:W was 75:25, it would be wrong because 25 is 33% of 75, not 25%.
