Shapes, One Set of Two Shapes, Two Colors - Pick One by Shape and Color, To Decimal (Level 2)

This math topic focuses on probability counting related to drawing shapes and colors from a bag, converting these probabilities into decimals. Students are asked to determine the likelihood of picking a specific colored shape (squares and circles in various colors) from a set. Each question provides multiple answer choices in decimal form, enhancing understanding of probabilities as decimals. This subject forms an introductory part of a broader unit on single-event probability and counting.

What is the chance, or probability, of drawing a yellow triangle from this bag of shapes?

Probability is the number of outcomes we want, or desired outcomes, divided by the total possible number of outcomes.

We can see that there are 2 ways to draw a yellow triangle, and there are 8 total ways to draw a shape, so our probability is 2 over 8

This simplifies to a probability of 1 over 4

We can also express this as a decimal, zero point two five, or as a percent, 25 percent, if we want.
