Grade 5 students push their probability and statistics skills further by analyzing line plots and bar graphs with larger counts and more varied data points than earlier sheets. They predict new probabilities when items leave or join the bag and calculate decimal means like 5.3 from frequency data tables carefully. The sheet prepares students well for sixth-grade ratios, proportions, and deeper data analysis throughout middle school math.

Probability and Statistics
Part A: Multiple Choice
Circle the best answer for each question.
1. A line plot has X's at 5(1), 6(3), 7(2), 8(4). What is the mode?
A) 8
B) 6
C) 7
D) 5
2. A bag holds 2 red, 3 blue, and 5 green marbles. What is P(blue)?
A) 3/5
B) 3/10
C) 5/10
D) 2/10
3. From the same bag, remove all green marbles. What is the new P(blue)?
A) 3/10
B) 2/5
C) 3/5
D) 1/2
4. A bar graph shows minutes 10, 20, 30, 40. What is the median?
A) 20
B) 30
C) 35
D) 25
Part B: Fill in the Blank
Write the correct answer on each line.
1. A bag has 5 red, 3 blue, 2 yellow marbles. P(yellow) = 2/10.
2. Add 5 more yellow to the same bag. New P(yellow) = 7/15.
3. A line plot has X's at 4(2), 5(3), 6(5). The mean is 5.3.
4. A bar graph shows scores 50, 60, 70, 80, 90. The mean is 70.
5. The same bar graph has a range of 40.
