A number is picked at random from the first three positive odd numbers.
A number is picked at random from the first four prime numbers.
The two numbers are multiplied to get a score.
Complete the table.

This question requires us to complete a sample space diagram for a probability problem. **Step 1: Identify the sets of numbers.** - The first three positive odd numbers are 1, 3, 5. The table shows 1 and 5, so the missing odd number is 3. - The first four prime numbers are 2, 3, 5, 7. (A prime number is a number greater than 1 that has only two factors: 1 and itself). The table shows 2, 3, and 7, so the missing prime number is 5. **Step 2: Fill in the table by multiplying.** The table shows the result of multiplying the odd number in the row by the prime number in the column. - **Top row (multiplying by 1):** 1×2=2, 1×3=3, 1×5=5, 1×7=7. - **Middle row (multiplying by 3):** 3×2=6, 3×3=9, 3×5=15, 3×7=21. - **Bottom row (multiplying by 5):** 5×2=10, 5×3=15, 5×5=25, 5×7=35. The value 15 is already given as a check.
