Given that Margie is practicing for an upcoming tennis tournament. Her first serve is good 20 out of 30 times on average.
Since each trial is independent and there are two outcomes, X no of good serves is binomial with n=6 and p =2/3

<h2>2 hours</h2>
Step-by-step explanation:
Easiest way to solve this is add and subtract till we get the values balanced.
Stock A
9 am $14.15
10 am $14.21
11 am $14.27
12 pm $14.33
1 pm $14.39
2 pm $14.45
Stock B
12 pm $14.65
1 pm $14.57
2 pm $14.45
Notice the bold values are the same at the same time 2 pm. If we start at 12 pm with stock B, it will be 2 hours before the prices are the same.
I'm always happy to help :)
