Problem
Adam has a bag with 16 green counters, 13 black counters and 21 white counters. Adam takes a counter from the bag at random. Find the probability that Adam takes a green counter.
Solution
Step 1 ：Find the total number of counters: \(16 + 13 + 21 = 50\)
Step 2 ：Calculate the probability of taking a green counter: \(\frac{16}{50} = \boxed{0.32}\)
