Answer:
1/3.
Step-by-step explanation:
P(event a occurs) = 3/9 = 1/3
P(event b occurs) = 3/9 = 1/3
P(a) ∩ P(b) = 1/3 * 1/3 = 1/9
P(b|a) = P(a) ∩ P(b) / P(a)
= 1/9 / 1/3
= 1/3.

Answer:
<u>The perimeter of the square is option E. 16√5 mm.</u>
<u>The area of the square is option A. 80 mm².</u>
Step-by-step explanation:
1. Let's calculate the perimeter of this square:
The perimeter of a square is the sum of its side 4 times, thus:
Perimeter = 4√5 + 4√5 + 4√5 + 4√5
<u>Perimeter = 16 √5</u>
<u>Perimeter = 4 * 4√5 = 16√5</u>
<u>The correct answer is option E. 16√5 mm</u>
2. Let's calculate the area of this square:
The area of a square is the length of its side squared, thus:
Area = (4√5)²
Area = 4√5 * 4√5
Area = (4 * 4 * √5 * √5)
Area = 16 * 5 = 80
<u>The correct answer is A. 80 mm²</u>
