Answer

Explanation:

Step1: Calculate total number of coins

$20 + 30+50=100$

Step2: Calculate theoretical probability

The number of one - dollar coins is 50. The theoretical probability $P_{theoretical}=\frac{50}{100}\times100% = 50%$

Step3: Calculate experimental probability

He picked 20 coins and 12 were one - dollar coins. The experimental probability $P_{experimental}=\frac{12}{20}\times100%=60%$

Answer:

50, 60
