Step-by-step explanation:
Use Multiplication Principle with states that if a event can occur n ways, and another mutually exclusive event occur p ways, then the total outcome is

The possible ways of rolling a dice is 6 and the possible ways of flipping a coin is 2 so we have

Now, we use the fact that proabliblity is
Number of favorable outcomes/ Total outcomes.
We can only get a head and a 5 once out of the set so the number of favorable outcomes is 1. Total outcomes is 12 so we have

A is the answer.
Answer:
2/9 and 7/4(or 1 3/4)
Step-by-step explanation:
A reciprocal is just the original number flipped.
Answer: A or C (i think A because its not including)
Step-by-step explanation:
I'm assuming that the lower case c and the upper case C are the same variables.
6C^2 + 2.5D - D + 2C^2 - 3D = 8C^2 - 1.5D
