There are 4 green counters 6 yellow counters and 2 red counters. What is the theoretical probability of picking a yellow counter in percent?
The total number of counters is 4 + 6 + 2 = 12.
The probability of picking a yellow counter is 6/12 = 0.5
To convert this to a percentage, multiply by 100:
0.5 * 100 = 50%
So, the theoretical probability of picking a yellow counter is 50%.
