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.
[tex]\text{Probability}=\frac{\text{Number of favorable outcomes}}{\text{Total number of possible outcome}}[/tex]
[tex]\text{Probability of getting tails in one flip}=\frac{1}{2}[/tex]
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.
[tex]\text{Possible number of getting tails in 100 flips}=\frac{1}{2}\times 100[/tex]
[tex]\text{Possible number of getting tails in 100 flips}=50[/tex]
Therefore, the coin will land about 50 times tails up in 100 flips.
Answer:
Close to 50 times but probably not exactly 50 times
