So what she wrote down is zx2x4 but you can simplify that to zx8 which then can be simplified to 8z. Which is the answer
64 divided by 4 is 16. The answer is 16 I believe!
Edit: I realized you were asking for the cost. That would be 48. 64 - 16 = 48.
Answer: 0.6
Step-by-step explanation:
The probability formula to find p(B/A) is :
P(B/A) = p(A n B) / p(B)
Which means that A is contain in B and p(A n B) is p(A)
p(A n B)= p(A)=0.6 × 0.05 = 0.03
p(B)=0.05
Therefore
P(B/A) = p(A n B) / p(B)=p(A) / p(B)
P(B/A)=0.03 / 0.05
P(B/A)=0.6
