Assuming twо pоssible gender оutcomes аmong newborn bаby whаles (male/female), and also assuming a 50-50 probability of male or female, answer the following questions. How many possible male/female outcomes are possible among 3 randomly selected baby whales? [outcomes] What is the probability of finding exactly 3 females among the 3 randomly selected baby whales? (round to 2 decimal places and report as a number, not a percent) [probf] Hint: Use the Fundamental Counting Rule to find the total possible outcomes, and the Combination rule to find how many ways to get exactly a certain number of outcomes from among the larger group. Finally, divide the latter from the former to find the probability.
