ight. \
ight\\}
points
\\( b = \\)

Explanation:

Step1: Identify the range

The range for \( y \) is \( 20 \leq y \leq 32 \), so we consider integers from 20 to 32 inclusive.

Step2: Identify odd numbers in the range

Odd numbers are numbers not divisible by 2. So we check each number in the range:

• 20: even (divisible by 2)
• 21: odd (not divisible by 2)
• 22: even
• 23: odd
• 24: even
• 25: odd
• 26: even
• 27: odd
• 28: even
• 29: odd
• 30: even
• 31: odd
• 32: even

So the odd numbers in the range are 21, 23, 25, 27, 29, 31.

Answer:

\( B = \{21, 23, 25, 27, 29, 31\} \)
