Last year, Khalil came in 2nd place in his school's Spelling Bee. This year, he plans to win 1st place. He compiled a long list of words to study, 51% of which have a Latin root. If Khalil randomly chooses a word to study from the list 2 different times this month, what is the probability that 0 of the words have a Latin root? Write your answer as a decimal rounded to the nearest thousandth. ____

Find Probability Without Latin Root: First, we need to find the probability that one word does not have a Latin root. Since 51% of the words have a Latin root, 100% - 51% = 49% of the words do not have a Latin root.Convert Percentage to Decimal: Now, we convert the percentage to a decimal to make calculations easier. So, 49% as a decimal is 0.49.Calculate Probability for Two Events: Next, we calculate the probability that Khalil chooses a word without a Latin root twice in a row. We multiply the probability of the first event by the probability of the second event, since the choices are independent. So, 0.49 * 0.49.Multiply Probabilities: Doing the multiplication, we get 0.49 * 0.49 = 0.2401.Round to Nearest Thousandth: Finally, we round the answer to the nearest thousandth as instructed. The rounded answer is 0.240.

Find Probability Without Latin Root: First, we need to find the probability that one word does not have a Latin root. Since $51\%$ of the words have a Latin root, $100\% - 51\% = 49\%$ of the words do not have a Latin root.
Convert Percentage to Decimal: Now, we convert the percentage to a decimal to make calculations easier. So, $49\%$ as a decimal is $0.49$ .
Calculate Probability for Two Events: Next, we calculate the probability that Khalil chooses a word without a Latin root twice in a row. We multiply the probability of the first event by the probability of the second event, since the choices are independent. So, $0.49 \times 0.49$ .
Multiply Probabilities: Doing the multiplication, we get $0.49 \times 0.49 = 0.2401$ .
Round to Nearest Thousandth: Finally, we round the answer to the nearest thousandth as instructed. The rounded answer is $0.240$ .
