<p>下圖是「資料庫」中某次抽球的過程，目前已經從藍罐抽出兩顆藍球，假設此次總共要抽三顆球，請問下次抽出<span style="color: red;font-weight:bold; font-size: 18px">紅球</span>的機率是多少？</p>

        <img src="{{ static 'risk/0.png' }}", width="100px" />
        <img src="{{ static 'risk/0.png' }}", width="100px" />
    </br></p>
{{ formfield 'Q1' }}
    {{ if is_Q1_correct }}
    <p class="solution-correct">
        正確
    </p>
    {{ else }}
    <p class="solution-incorrect">
        錯誤，本題答案為 A. ，在資料庫抽球的過程中，抽球是取後放回，且每顆球被抽中機率相等。因此抽中紅球機率是1/3。
