Answer:
50 times.
Step-by-step explanation:
We have been given that Elizabeth is going to flip a fair coin 100 times. We are asked to find the number of times the coin will land tails up.
Since we know that a fair coin has two equally likely possible outcomes and each flip has an equal chance of coming up heads or tails.
To find the number of times the coin will land tails up we will multiply the probability of getting tails in one flip by the number of times coin was flipped.
Therefore, the coin will land about 50 times tails up in 100 flips.
