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:
Step-by-step explanation:
Slope is 1/3 and the y intercept is (0,-3), if you plug these answers into slope intercept form (y=mx+b) you get this answer
2x - 10 = 4x - 8
-10 = 2x - 8
-2 = 2x
-1 = x
The answer would be c I think
Subtract 3.25x from 6.75x, which results in 3.5x
