3.3.1. An urn contains five balls numbered 1 to 5. Two balls are drawn simultaneously. (a) Let X be the larger of the two number

hodyreva [135]

Answer:

Step-by-step explanation:

Given that an urn contains five balls numbered 1 to 5

Two balls are drawn simultaneously.

a) X = the larger of two numbers drawn

Assuming balls are drawn without replacement, (since simultaneously drawn)

the sample space would be (1,2) (1,3)(1,4)(1,5) (2,3)(2,4)(2,5) (3,4) (3,5) (4,5)

n(S) = 10

n(x=2) = 1,

n(x=3) =2

n(x=4) = 3

n(x=5) = 4

Larger value X can take values only as 2,3,4 or 5

X 2 3 4 5

p 0.1 0.2 0.3 0.4

-------------------------------------------

b) V = sum of numbers drawn

V can take values as 3, 4, 5, 6, 7, 8 or 9

V 3 4 5 6 7 8 9

p 0.1 0.1 0.2 0.2 0.2 0.1 0.1

What is the measure of arc ADB? What is the length of arc ADB? What is the area of the shaded region?

FrozenT [24]

What is the measure of arc ADB?
The measure of the arc for this case is given by the following angle:
theta = 360-90
theta = 270 degrees

What is the length of arc ADB?

The arc length is given by:
s = R * theta
Substituting values:
s = 15 * (270 * (pi / 180))
s = 70.69 m

What is the area of the shaded region?

The area of the shaded region is:
A = (s' / s) * (pi) * (r ^ 2)
Substituting values:
A = (270/360) * (3.14) * (15 ^ 2)
A = 529,875 m ^ 2

Tyler made a picture graph to show students favorite color .this is the key for his graph

Tanzania [10]

This is an example of a Circle Graph, a circle graph is like a Pie chart, and In graph theory, a circle graph is the intersection graph of a set of chords of a circle. That is, it is an undirected graph whose vertices can be associated with chords of a circle such that two vertices are adjacent if and only if the corresponding chords cross each other.

Look at the graph I showed you

Hope it helped
