Thomas is rolling a fair six-sided number cube numbered from 1 to 6. The situation with a probability closest or equal to 0 is ___________________. * Rolling a number greater than 1 Rolling a 1 Rolling a number less than 1 Rolling a odd number For a class activity, each student randomly chooses a number from 1 to 10. Which model shows the probability of a student choosing a multiple of 4? * 2/8 2/10 8/2 10/2 A bag contains 4 white, 3 blue, and 3 red marbles. Find the probability of choosing a red marble, then a white marble if the marbles are replaced. * 7/10 7/100 12/90 12/100 Find the probability of spinning P(not 7) * 1/7 1/8 7/8 4/8 Sonya is thinking of conducting a survey with her seventh-grade classmates.

1. The situation with a probability closest or equal to 0 is: **Rolling a number less than 1**. (Since the die is numbered from 1 to 6, rolling a number less than 1 is impossible.)
2. The model that shows the probability of a student choosing a multiple of 4 when randomly choosing a number from 1 to 10 is: **2/10**. (The multiples of 4 in that range are 4 and 8, so that's 2 successful outcomes out of 10 possible outcomes.)
3. The probability of choosing a red marble, then a white marble if the marbles are replaced is: **12/100**. (The probability of choosing a red marble is 3/10 and the probability of choosing a white marble is 4/10, so the combined probability with replacement is (3/10) * (4/10) = 12/100.)
4. The survey that would not be valid with a sample of seventh-grade classmates is: **bank that offers the most services**. (This is likely aimed at a broader audience than just seventh graders, making it less relevant for that specific demographic.)
