Algebra.Com's Answer #849240 by CPhill(1959)![]() ![]() You can put this solution on YOUR website! Here's how to calculate the probability:\r \n" ); document.write( "\n" ); document.write( "1. **Probability of a correct answer on the first question:** There are 3 possible answers, and only 1 is correct. So the probability of guessing correctly is 1/3.\r \n" ); document.write( "\n" ); document.write( "2. **Probability of a correct answer on the second question:** There are 5 possible answers, and only 1 is correct. So the probability of guessing correctly is 1/5.\r \n" ); document.write( "\n" ); document.write( "3. **Probability of both answers being correct:** Since the guesses are independent events, we multiply the probabilities:\r \n" ); document.write( "\n" ); document.write( " (1/3) * (1/5) = 1/15\r \n" ); document.write( "\n" ); document.write( "4. **Convert to a percentage:**\r \n" ); document.write( "\n" ); document.write( " (1/15) * 100% ≈ 6.67%\r \n" ); document.write( "\n" ); document.write( "Therefore, the probability that both responses are correct is approximately 6.67. \n" ); document.write( " \n" ); document.write( " |
