• "grows by" or "increases by a fixed percentage"

• "leaves the money" (implying a set amount deposited)

• "for _ years" (referring to a fixed period)

• “set aside an amount today” or “needs to deposit now”

• “to have _____ in __ years” (indicating a future target amount)

• “compound interest” with a rate over time

• “save up” or “accumulate” for a specific goal

• “contribute at the end of each period” (implying regular deposits)

• “earn ___ interest compounded ___”

• “equivalent value of payments today” or “worth now”

• “annuity that pays ___ per month for ___ years” (implying a fixed payment steam over time)

• “discount rate” or “interest rate applied”

• “deposits” or “initial amount” without regular contributions

• “earns ___% interest compounded ___” over time

• “will he have in ____ years?” (target balance in the future)

• “save ___every period” or “contributes regularly”

• “will he have at the end of ____ years?” (implying future total of periodic deposits")

• “earns ___ interest compounded ___”

• “financed through a loan” or “monthly payments”

• “loan term of ___ years” with a specific interest rate

• “monthly payment”

• “how many ways” with specific positions or roles (implies ordering matters)

• “selected for specific roles” or “arranged in a specific order”

• “unique positions”

• “what is the probability of” followed by an ideal outcome (ex: specific number or color)

• “each outcome is equally likely”

• “spinner, coin, or dice” with phrases indicating equal chance for outcomes (standard setup in theoretical prob)

• “based on this data” or “from this sample” (indicates observed or past data)

• “what is the probability that” with data collected from real trials or events

• “in a sample of,” “recorded number of successes out of total trials” (points to empirical prob)

• “use the frequency table to determine/count” (suggests data tabulation for observed frequencies)

• “how many students read,” “number of occurrences of,” “frequency of” (asks for counts or frequency of a category)

• “data on” with specific categories or counts (indicates data organized in a frequency table)

• “probability of each outcomes” or “probability of a specific value”

• “table shows probability of” with distinct outcomes or values

• “exactly,” “less than,” or “more than” (indicates using values in the distribution to find a specific prob)
