he could by 8 movie tickets

66/8,25=8

**Answer:**

0.347

**Step-by-step explanation:**

n = 3

p = 1/6

r = 1

Use binomial probability:

P = nCr pʳ qⁿ⁻ʳ

P = ₃C₁ (1/6)¹ (5/6)³⁻¹

P = 0.347

Or, using a calculator:

P = binompdf(n, p, r)

P = binompdf(3, 1/6, 1)

P = 0.347

**Answer:**

11=y

**Answer:**

**Option C : f+23 is the correct answer.**

**Step-by-step explanation:**

Given that:

Amount Dominic wants everyone to contribute = $2

Number of relatives who have contributed = 23

The expression is;

2(f+23)

As we know that 2 represents the amount and 23 represents the number of relatives who have donated, therefore,

f represents the number of people who would donate to the library fund, and

f+23 represents the total number of people who contributes to the fund.

Hence,

**Option C : f+23 is the correct answer.**

Answer:a is 40 degrees

b is 140 degrees

Step-by-step explanation:

The given polygon has 5 irregular sides. This means that it is an irregular pentagon. The sum of the exterior angles of a polygon is 360 degrees

The exterior angles of the given pentagon are a, 75, 65, 60 and 120. Therefore

a + 75 + 65 + 60 + 120 = 360

a + 320 = 360

Subtracting 320 from both sides of the equation, it becomes

a = 360 - 320 = 40 degrees

The sum of angles on a straight line is 180/degrees. Therefore,

a + b = 180

b = 180 - a = 180 - 40 = 140 degrees
