Let’s go through each question one by one, carefully and step by step.

Question 1: What is the probability of choosing the letter “i” from the word “probability”?
First, let’s count how many letters are in the word
probability.
Write it out:
p - r - o - b - a - b - i - l - i - t - y → that’s
11 letters total.
Now, how many times does the letter
“i” appear?
Looking again: positions 7 and 9 →
two “i”s.
So, probability = (number of favorable outcomes) / (total number of possible outcomes)
= 2 / 11
✔ Correct answer:
A. 2/11

Question 2: Is the spinner more likely or less likely to land on green than yellow?
Look at the spinner sections:
- Green appears
3 times
- Yellow appears
1 time
Since there are more green sections than yellow, the spinner has a higher chance of landing on green.
So, it is
more likely to land on green than yellow.
✔ Correct answer:
B. more likely

Question 3: Is it certain or impossible for the spinner to land on orange?
Check all the colors on the spinner: Blue, Red, Green, Yellow — no Orange anywhere.
If a color isn’t on the spinner at all, you can never land on it.
That means it’s
impossible.
✔ Correct answer:
A. impossible
---
Question 4: What is the probability of the spinner landing on an odd number?
The spinner has numbers: 1, 2, 3, 4, 5, 6, 7, 8 → total of
8 sections.
Odd numbers among them: 1, 3, 5, 7 → that’s
4 odd numbers.
Probability = 4 / 8
We can simplify that to 1/2, but since 4/8 is one of the options, and it’s mathematically correct, we pick that.
✔ Correct answer:
D. 4/8

Final Answer:
1. A
2. B
3. A
4. D
