For Exercises 81–82, use the formula pH = - log [ H + ] . The variable pH represents the level of acidity or alkalinity of a liquid on the pH scale, and H + is the concentration of hydronium ions in the solution. Determine the value of H + (in mol/L) for the for the following liquids, given their pH values. a. Milk pH = 6.2 b. Sodium bicarbonate pH = 8.4

Amy and Samiha have a hat that contains two playing cards, one ace and one king. They are playing a game where they randomly pick a card out of the hat four times, with replacement.
Amy thinks that the probability of getting exactly two aces in four picks is equal to the probability of not getting exactly two aces in four picks. Samiha disagrees. She thinks that the probability of not getting exactly two aces is greater.
The sample space of possible outcomes is listed below. A represents an ace, and K represents a king. Who is correct?
