Question

Elizabeth is going to flip a fair coin 100 times. What is the best prediction for the number of times that the coin will land tails up?

Answer 1

Close to 50 times but probably not exactly 50 times

Explanation:

Answer 2

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.

`\text{Probability}=\frac{\text{Number of favorable outcomes}}{\text{Total number of possible outcome}}`

`\text{Probability of getting tails in one flip}=(1)/(2)`

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.

`\text{Possible number of getting tails in 100 flips}=(1)/(2)* 100`

`\text{Possible number of getting tails in 100 flips}=50`

Therefore, the coin will land about 50 times tails up in 100 flips.
