She is correct.
Triangles QPS and QRS are congruent by SSS since all sides of one triangle are congruent to corresponding sides of the other triangle. Two pairs of sides are marked as congruent, and the third side, QS, is congruent to itself.
Then by CPCTC, angles P and R are congruent.

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)
Hope this helps
Have a great day!
Option C : f+23 is the correct answer.
Amount Dominic wants everyone to contribute = $2
Number of relatives who have contributed = 23
The expression is;
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.
Answer:a is 40 degrees
b is 140 degrees
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
