Answer:
3686
Step-by-step explanation:
The sinusoid makes a complete oscillation (i.e. 360°) every 3 seconds. So, in one second it makes 1/3 of a turn, leading to 360°/3 = 120°.
So, the correct answer is the last one.
Answer:
5/6
Step-by-step explanation:
There is a 1 out of 2 chance that you will roll tails, so the probability is 1/2.
A number less than three is a 2 and 1, so the probability is 2/6.
Add 1/2 + 2/6. (Change 1/2 to 3/6 so you can add.)
3/6 + 2/6 = 5/6
