What all of them and if u need all of them give me a second
Answer:
you must understand the formal
and then take a step to solve the question you are giving for example when you are given to fine √81.first you must understand what they are you to do
A= a+b over 2 times height
18 + 8 = 26
26 divide by 2 = 13
13 x 6 = 78
area is 78
Answer:
Step-by-step explanation:
The probability of an event to occur is given by a fraction:

Your favourable cases are given by the number of red face cards, that is the Jacks, the Queens and the Kings of Diamonds and Hearts, this number is 6.
