Question

Monique uses a random number generator to simulate the results of a coin

toss. She assigns the number 0 to heads and the number 1 to tails. If 800
numbers are generated, how many tails can she expect?

Answer 1

400

verified on a p e x

Answer 2

She can expect 400 tails.

Explanation:

When doing a coin toss, the theoretical probability of getting either heads or tails is 1/2. If we apply this fraction to the 800 total simulated tosses, she should get about 400, more or less.
