SkillrHub Practice guide

Each attempt draws five questions from the full bank. Repeat an attempt to meet more questions.

Worked model: Bag A has 10 red and 5 white balls; B has 20 of each; C has 25 red and 20 white. Least to most likely to draw red?
  • Worked answer: B, C, A. B is balanced. C has a small red advantage. A has two red for each white, a greater red share than C.
  • Check your reasoning: List all available outcomes and compare their stated counts or equal sectors.
  • Materials and practical tasks: State the possible outcomes and the conditions. Have counters or a spinner ready for practical tasks, and distinguish a likely outcome from a certain outcome.
  • Written responses: An adult checks your completed work against the task-specific guidance before awarding credit.
