We know that
the addition rule states that
P(A or B) = P(A) + P(B) − P(A and B)
in this problem
P(A)=0.72
P(B)=0.84
P(A and B)=0.64
so
P(A or B) = P(A) + P(B) − P(A and B)-----> 0.72+0.84-0.64
P(A or B) = 0.92
the answer is
0.92 (92%)
Answer:
20.669
Step-by-step explanation:
using pythagorean theorem
a^2 + b^2 =c^2
a^2 +8^2 =14^2
a^2 +64 = 196
subtract 64 from each side
a^2 = 132
take the square root of each side
a^2 = sqrt (132)
a=11.48912529
a =11.5
For this case we have the following property of the sum:

What we need to know is that the name of this property is:
Identity property of the sum.
What this property establishes is:
Every number added to zero is equal to the same number.
Answer:
the number sentence show:
Identity property of the sum.
