The length of AB is 18.9 unit
Answer:hi
Step-by-step explanation:
X×-3+6=12, -3×=12-6, -3x=6 |÷-3, x=-2
If each of A, B, and C are mutually independent, then
P(A and B and C) = P(A) P(B) P(C)
so that the probability of the three-way intersection is
P(A and B and C) = 0.66 × 0.52 × 0.78 = 0.267696 ≈ 0.27
