In order from least to greatest, it goes 4/5, 0.81, 90%
Answer:
probability the spy is able to unlock the tablet on his first try.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
Desired outcomes:
1 correct password, so 
Total outcomes:
Nine-digit codes.
For each digit, there are 10 possible outcomes. So
What is the probability the spy is able to unlock the tablet on his first try?
probability the spy is able to unlock the tablet on his first try.
Given:
Shapes: Trapezoid and Triangle.
Trapezoid: Upper base = 14mm ; lower base = 18mm
Triangle: base = 18mm ; height = 12mm
Total height of the figure is 17 mm
Area of a trapezoid = (upper base + lower base)/2 * height
A = (14mm+18mm)/2 * (17mm-12mm)
A = 32mm/2 * 5mm
A = 16mm * 5mm
A = 80 mm²
Area of a triangle = (height * base) ÷ 2
A = (12mm * 18mm) ÷ 2
A = 216mm² ÷ 2
A = 108 mm²
Total area of the figure = 80 mm² + 108 mm² = 188mm²
