Question 1: Step 1: The above figure is an 8-point spinner. There are a total of 8 sections of colours. Step 2: The probability of landing the spinner on blue section is - 2/8 = 1/4. Answer: C. 1/4 Question 2: Step 1: In a bag of a dozen marbles, three are red. The number of marbles that are not red is 12 - 3 = 9. Step 2: Jane randomly picks one marble from the bag. The probability of picking a marble that is not red is - 9/12 = 3/4 Answer: E. 3/4 Question 3: Step 1: A regular 6-sided dice is thrown. Step 2: The probability of landing the dice on 1 is - 1/6. Answer: A. 1/6 Question 4: Step 1: Elmo flipped a fair coin. ©Scholarly 2025. All rights reserved. All digital content and materials provided are proprietary and protected under copyright law.

The coin has two sides where one is heads and another is tails. Step 2: The probability that the coin will land on heads is 1/2. Answer: B. 1/2 Question 5: Step 1: There are 52 cards in a deck, and the cards are numbered 1 to 13. There are 4 cards of each number in the deck. You insert 12 more cards with the number 10 on them. So, previously there are 4 cards with the number 10 on them, further you insert 12 more cards with the number 10 on them. Total number of cards with number 10 on them is - 4 + 12 = 16 cards. Step 2: Total number of cards after inserting 12 more cards is - 52 + 12 = 64. The probability of pulling a card with a number 10 on it is - 16/64 = 1/4. Answer: B. 1/4 Question 6: Step 1: There are a total 20 shapes in the above set. 40% of 20 is - 20 * 40% = 8. So, there must be 8 shapes in order to get a 40% chance of being selected. Step 2: There are 8 yellow stars. So, yellow stars have a 40% chance of being selected. Answer: A. ©Scholarly 2025. All rights reserved.

Question 7: Step 1: A box contains 24 balls, of which 12 are blue and 12 are green. Step 2: The probability of selecting a green ball is - 12/24 = 1/2. Answer: E. 1/2 Question 8: Step 1: Twenty cards are numbered from 1 to 20. Step 2: There are 10 even numbers from 1 to 20. The probability of selecting a card that has even number is - 10/20 = 1/2. Answer: A. 1/2 Question 9: Step 1: Jenny rolls a regular six-sided. Step 2: The probability that a dice will not land on 6 is 5/6. Answer: E. 5/6 Question 10: Step 1: A bag of marbles contains twice as many red marbles as blue marbles. These are the only colours of marble in the bag. Say there are x blue marbles and 2x red marbles. Step 2: The probability of randomly picking a blue marble is - x/(2x + x) = x/3x ©Scholarly 2025. All rights reserved.

x/3x = 1/3. Answer: C. 1/3 Question 11: Step 1: The above figure is a 12-point spinner. Step 2: The probability of landing the spinner on 1 is - 3/12 = 1/4. Answer: D. 1/4 Question 12: Step 1: The circle below is divided into eight equal sections. Step 2: A point is selected at random from the circle. The probability that the point selected is located in any of the yellow-coloured sections is - 2/8 = 1/4. Answer: D. 1/4 Question 13: ©Scholarly 2025. All rights reserved.
