if you were to flip the coin 15 times, how many times will the coin land on tails based on the experimental probability? show your work in the box below the image.
Answer
Explanation:
Step1: Calculate experimental probability of tails
The total number of coin - flips in the experiment is $24 + 21=45$. The experimental probability of getting tails $P(T)$ is $\frac{21}{45}=\frac{7}{15}$.
Step2: Predict number of tails in 15 flips
Let $x$ be the number of tails in 15 flips. We set up a proportion: $\frac{x}{15}=\frac{7}{15}$. Cross - multiplying gives $15x = 7\times15$. Solving for $x$, we get $x = 7$.
