RNG--Mr. Pham put pieces of paper with numbers on them in a bag and gave it to Ms. Tsang. She pulled out the following numbers:
5, 8, 10, 12, 1
Ms. Tsang says the probability for selecting an odd number out of the bag is probably 20%. Explain whether you agree or disagree with her.
"I (agree / disagree) with Ms. Tsang because..."
