One spinner has three equally sized sectors numbered 1, 2, and 3. A second spinner has two equally sized sectors labeled Top (T) and Bottom (B). Each spinner is spun once.

What is the sample space of outcomes?
{1, 2, 3, T, B}

{BT, 123}

{B1, B2, B3, T1, T2, T3}

{BT, BB, TB, 11, 12, 13, 21, 22, 23, 31, 32, 33}

I chose C
