Grade 4 Probability quiz featuring questions on likelihood and probability using visual aids like a bag of balls, a spinner, a die, and a pie chart.

Let’s solve each problem one by one, step by step.

---

Problem 1:

We are looking at a bag with colored balls. Let’s count them:

- Green balls: There are 4 green balls.
- Red balls: There are 6 red balls.
- Total balls = 4 (green) + 6 (red) = 10 balls

Probability of picking a green ball = (Number of green balls) / (Total number of balls)
= 4 / 10

So the answer is 4/10

Check options:
A) 4/6 → too small total
B) 4 → not a probability (should be fraction or decimal)
C) 1/2 → that would be 5 out of 10, but we have only 4 green
D) 4/10 → matches!

✔ Correct answer for #1: D

Problem 2:

Spinner divided into sections. Let’s count how many sections there are and how many are yellow.

Looking at the spinner:

It has 12 equal sections (you can count them around the circle).

Yellow appears in only 1 section.

So likelihood of getting yellow = 1 out of 12

Check options:
A) 3 out of 12 → too many yellows
B) 5 out of 7 → wrong total
C) 1 out of 8 → wrong total
D) 1 out of 12 → correct!

✔ Correct answer for #2: D

Problem 3:

Rolling a standard die — it has 6 faces: 1, 2, 3, 4, 5, 6.

We want to land on a 3.

Only one face shows a 3.

So likelihood = 1 out of 6

Check options:
A) 3 out of 6 → that’s half, too high
B) 1 out of 8 → die doesn’t have 8 sides
C) 1 out of 6 → perfect!
D) 5 out of 7 → nonsense for a die

✔ Correct answer for #3: C

Problem 4:

Spinner with colors: orange, red, yellow, blue.

We need to see which color takes up the biggest area, because “MOST likely” means largest section.

From the picture:

- Orange covers almost half the circle → biggest slice
- Red is next, smaller than orange
- Yellow and blue are tiny slices

So Mariana will MOST likely land on orange

But wait — the question says “she will MOST likely land on –” and then gives no multiple choice? Actually, looking back, this might be incomplete in your image, but based on what’s shown, the answer should be orange.

However, since you didn’t provide answer choices for #4, and the instruction says to pick from given options if available — but here none are listed — I’ll assume the expected answer is just the word “orange”.

But let me double-check: In some versions of this quiz, the options might be implied or cut off. Since the user didn’t include options for #4, and our job is to solve accurately — we go by logic.

Largest section = orange → most likely outcome.

✔ So answer for #4: orange
