The algorithm below is used to simulate the results of flipping a coin 4 times. Consider the goal of determining whether the simulation resulted in an equal number of heads and tails.

• Step 1: Initialize the variables heads_counter and flip_counter to 0.
• Step 2: A variable coin_flip is randomly assigned a value of either 0 or 1. If coin_flip has the value of 0, the coin flip result is heads, so heads_counter is incremented by 1.
• Step 3: Increment the value of flip_counter by 1.
• Step 4: Repeat steps 2 and 3 until flip_counter equals 4.

Following execution of the algorithm, which of the following expressions indicates that the simulation resulted in an equal number of heads and tails?

Summary Submit

After every simulation, the the heads_counter will increase by 1 if a heads was obtained by the coin flip. The simulation stops after the flip_counter equals 4, implying that there are 4 flips. Therefore we need 2 heads.
