Answer:
24
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:
[tex]\frac{7\text{ heads}}{15}=\frac{x}{45}[/tex]
Where x is the number of heads that he gets when he flips the coin 45 times. So, solving for x, we get:
[tex]\begin{gathered} \frac{7}{15}\times45=\frac{x}{45}\times45 \\ 21=x \end{gathered}[/tex]
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.
