Answer:
coin 1
Step-by-step explanation: i think this is it
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%)
1st perinthesis: 3/4 - 1/4 = 2/4 = 1/2
15/24 - 10/24 =5/24
5/24(1/2) = 5/48
5/48 + 32/48 = 37/48
so the answer is 37/48
Answer:
y^3
Step-by-step explanation:
- y^15-12
two negatives is a positive
2+2x= 19+2x
<u> -2x= -2x</u> (they both cross out)
2= 19
there is no solution for x
