Step 2. Find modulus |z|

|z|= check mark 3 to the power of 2 + (-3) power of 2 = check mark, 9+9 = check mark 18 =check mark 9.

Step 3. Write out z in polar form

z = 3 check mark 2.

what is the chance to get 4 items with 10% chance of each occurring, while there 8 items in total with other 4 items having a 90
densk [106]

Step-by-step explanation:

Simple events in probability have a certain chance of happening. For example, a 10% chance of rain today. When two or more probabilities are possible, they are added together to get the total probability. A 10% chance of snow and a 15% chance of hail would mean a 10% + 15% = 25% chance of bad weather. This article will show you how to find the probability of a simple event happening.
