May you please help me??

14:00

Step-by-step explanation:

We have to add to the initial time the times that are consumed with each activity:

First time: 7:00

7hours 0 minutes

Three surgeries x two hours = 6 hours

7hours 0 minutes + 6 hours = 13hours 0 minutes

He drives 30 minutes

13 hours 0 minutes + 30 minutes = 13hours 30 minutes

He eats a snack 30 minutes

13hours 30 minutes + 30 minutes = 13 hours 60 minutes = 14hours 0 minutes

14:00

one that is bigger than 3 1/2

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
