(3 - i) + (1 - 2i)
= 3 + 1 - i - 2i
= 4 - 3i
Hi hope this helps anyways im pretty sure its c i did the math sorry if im wrong but i think its c
Answer:
a) The probability that a 5 is rolled is 
b) The probability that a number greater than 2 is rolled is 
Step-by-step explanation:
a)
On this cube, there are sides labeled 1-6. Only one of the six sides is labeled 5. This means that the probability of rolling a 5 is 
b)
Again this cubes has sides labeled 1-6.
The numbers on the cube that are greater than 2 are 3,4,5, and 6. This is 4 of the 6 sides of the cube.
when simplified is 
5/6 of the marbles are red or blue. Since half of the marbles are red, you can convert that to sixths which would be 3/6. You can also convert the number of blue marbles into sixths, and 1/3 is equal to 2/6. When you ad the number of blue marbles to the number of red marbles, you get 5/6. I hope this helps you understand the question better.
