Answer:
28.347 %
Step-by-step explanation:
by using binomial expansion
P = 12C2•(80%)^10•(20%)^2 = 23.347 %

We're willing, but sadly not able.
Here's are the other things we'll need before we can attack this one:
1). We need to know how often does Ned swim ?
2). We need to know how often does Ned bicycle ?
3). We need to see that "chart below".
The only thing I see below right now is my dog.
30-60-90
hyp = 2 * short leg
Long log = √(3) * short leg
long leg = 25√3
Answer:
The smallest angle is 32 degrees
Step-by-step explanation:
The given parameters show that the triangle is a right angled triangle;
Let the two other angles be represented by x and y;
Since the angle between side 5 cm and side 8 cm is 90, we can represent any of this sides as the opposite and as the adjacent;
Scenario 1 (Calculating x)
Let opposite = 5 cm
Let adjacent = 8 cm
In trigonometry, The relationship between opposite and adjacent is Tangent;
Take arctan of both sides
(Approximated)
Scenario 2 (Calculating y)
Let opposite = 8 cm
Let adjacent = 5 cm
In trigonometry, The relationship between opposite and adjacent is Tangent;
Take arctan of both sides
(Approximated)
<em>By comparing the angles, the smallest angle is 32 degrees</em>
