A bag contains 15 black, 17 green, 22 pink, and 29 yellow tokens. You pick one token at random. Find the probability that it is pink or yellow. P(pink or yellow) \( = \) [?]

To find the probability of picking either a pink or a yellow token, first, calculate the total number of tokens. Total tokens = 15 (black) + 17 (green) + 22 (pink) + 29 (yellow) = 83 tokens. Now, the number of favorable outcomes (pink or yellow tokens) = 22 (pink) + 29 (yellow) = 51. Thus, the probability is given by the formula: \[ P(pink \, or \, yellow) = \frac{favorable \, outcomes}{total \, outcomes} = \frac{51}{83} \] So, \( P(pink \, or \, yellow) = \frac{51}{83} \).
