Step 1: Calculate the probability of both spins being green. - The probability of one spin being green is \( \frac{1}{4} \). - The probability of the second spin being green is also \( \frac{1}{4} \). - The combined probability of both spins being green is \( \left(\frac{1}{4}\right) \times \left(\frac{1}{4}\right) = \frac{1}{16} \). Step 2: Calculate the probability of both spins being xanh lơ. - The probability of one spin being xanh lơ is \( \frac{2}{4} = \frac{1}{2} \). - The probability of the second spin being xanh lơ is also \( \frac{2}{4} = \frac{1}{2} \). - The combined probability of both spins being xanh lơ is \( \left(\frac{1}{2}\right) \times \left(\frac{1}{2}\right) = \frac{1}{4} \). Step 3: Calculate the probability of first green and then xanh lơ. - The probability of the first spin being green is \( \frac{1}{4} \). - The probability of the second spin being xanh lơ is \( \frac{2}{4} = \frac{1}{2} \). - The combined probability of first green and then xanh lơ is \( \left(\frac{1}{4}\right) \times \left(\frac{1}{2}\right) = \frac{1}{8} \). Step 4: Calculate the probability of first orange and then xanh lơ. - The probability of the first spin being orange is \( \frac{1}{4} \). - The probability of the second spin being xanh lơ is \( \frac{2}{4} = \frac{1}{2} \). - The combined probability of first orange and then xanh lơ is \( \left(\frac{1}{4}\right) \times \left(\frac{1}{2}\right) = \frac{1}{8} \). Step 5: Calculate the probability of first orange and then green. - The probability of the first spin being orange is \( \frac{1}{4} \). - The probability of the second spin being green is \( \frac{1}{4} \). - The combined probability of first orange and then green is \( \left(\frac{1}{4}\right) \times \left(\frac{1}{4}\right) = \frac{1}{16} \). Options 1, 2, and 4 are correct.
