Question

Ben flipped a coin and got heads715of the time. If he flipped the coin 45 more times, how many times would you expect Ben to flip tails? 7 283524

Answer 1

24

Step-by-step explanation:

First, we will calculate the number of heads when he flipped the coin 45 more times. So, we will use the ratio 7/15 as:

`\frac{7\text{ heads}}{15}=(x)/(45)`

Where x is the number of heads that he gets when he flips the coin 45 times. So, solving for x, we get:

`\begin{gathered} (7)/(15)*45=(x)/(45)*45 \\ 21=x \end{gathered}`

Then, if 21 times of the 45 we get head, the number of times that we get tails is:

45 - 21 = 24

Therefore, you would expect to flip tails 24 times.
