S -------------------------- 0.3
T -------------------------- 0.3
A -------------------------- 0.1
I --------------------------- 0.2

Step-by-step explanation:
Given
Solving (a): Outcomes and Probabilities
The text is made of the following makeup.
The probability of each outcome is calculated by dividing the occurrence of each alphabet by the total number of alphabets
So:
In tabular form, we have:
Outcome ---------- Probability
S -------------------------- 0.3
T -------------------------- 0.3
A -------------------------- 0.1
I --------------------------- 0.2
S -------------------------- 0.1
Solving (b)
Calculating P(V)
P(V) = Number of vowels divided by total
The vowels are A and I.
So, number of vowels is 2
Calculating P(F)
P(F) = Number of alphabets from A to M divided by total
Alphabets from A and M are A and I
So, number of alphabets in this category is 2
So:
Solving (c):
Events V and F are not mutually exclusive because both can occur at the same time.
i.e.
An event can be a vowel and still be between A and M
Answer:
2nd option
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c
Given
- 3x - 2y = 30 ( add 3x to both sides )
- 2y = 3x + 30 ( divide terms by - 2 )
y = - x - 15 ← in slope- intercept form
