The numbers 1-10 are placed in a bag. Each student draws a number and then makes a statement about the probability. If the probability of selecting the number is 3/10, then what could the question be?

• What is the probability of drawing a number greater than 7?

• What is the probability of drawing an even number?

• What is the probability of drawing a number less than 4?

• What is the probability of drawing a prime number?
