Ben flipped a coin and got heads 7/15 of the time. If he flipped the coin 45 more times, how many times would you expect Ben to flip tails?

Im pretty sure its 21
This is because 7/15 as a percentage is 46.6 and then 46.6 percent of 45 is 21

Answer:

22 times

Explanation:

just to be clear i don't know if thats right because you can't actually expect which way a coin is going to flip so its all up to chance but anyways...

1. 7 is about half of 15 and 22 is about half of 45 (you could also do 23 or 22.5 if you want to be exact)
