Let’s go through each question one by one.
---
Question 1:
What is the probability of choosing the letter
i from the word
probability?
Step 1: Count total letters in “probability” → p-r-o-b-a-b-i-l-i-t-y → that’s 11 letters.
Step 2: Count how many times the letter
i appears → it appears twice (positions 7 and 9).
Step 3: Probability = favorable outcomes / total outcomes = 2/11.
Looking at options:
A) 2/11
✔
B) 1/10
C) 1/10
D) 2/2
So correct answer is A.

Question 2:
Is the spinner more likely or less likely to land on green than yellow?
Look at the spinner:
- Green sections: 3
- Yellow sections: 1
Since there are more green sections than yellow, it’s
more likely to land on green.
Options:
A) less likely
B) more likely
✔
Correct answer: B

Question 3:
Is it certain or impossible for the spinner to land on orange?
Look at the spinner colors: Blue, Red, Green, Yellow — no orange anywhere.
So, landing on orange is
impossible.
Options:
A) impossible
✔
B) certain
Correct answer: A

Question 4:
What is the probability of the spinner landing on an odd number?
Spinner has numbers: 1, 2, 3, 4, 5, 6, 7, 8 → 8 total sections.
Odd numbers: 1, 3, 5, 7 → that’s 4 odd numbers.
Probability = 4/8 = 1/2.
But let’s check the options:
A) 1/3
B) 4/4
C) 1/4
D) 4/8
✔
Note: 4/8 is correct, even though it simplifies to 1/2 — but since 4/8 is listed, we pick that.
Correct answer: D

Final Answers:
1. A

4. D
Final Answer:
A, B, A, D
