Answer:
Mary worked 7 and a half hours.
Step-by-step explanation:
The easiest way to solve this is converting to the 24 hours metric.
In this metric, 8:10 am is 8h, 10 min.
3:45 pm is 12+3 = 15h, 45 min.
Rounded to the nearest quarter hour, Mary worked 15-8 = 7h, 45-10 = 35 min, Mary worked 7 and a half hours.
I There would be 52-4 = 48 cards that are not aces.
The probability of picking a non ace card would be 48 out of 52, which is written as 48/52, which reduces to 12/13
g = h(e-10)
You can multiply the whole equation by h to get g by itself.
