Quantity I: A coin is tossed 3 times. What is the probability of getting a tail each time? Quantity II: \(\frac{1}{16}\)

Quantity I > Quantity II
Quantity I < Quantity II
Quantity I ≥ Quantity II
Quantity I ≤ Quantity II

Correct answer: Quantity I > Quantity II

Solution

The probability of getting a tail on each of 3 tosses is \((1/2)^3 = 1/8\). Since \(1/8 > 1/16\), Quantity I is greater than Quantity II.
