Probabilities with Playing Cards Part 1

Probabilities with Playing Cards Part 1 is a Grade 7 whole-class investigation of dependent probability using one suit of cards. Students begin with simple one-card probabilities, then remove a card without replacement and calculate how the first event changes the probability of the second. Examples such as drawing a queen and then a jack make the changing denominator visible.

Use it when students are first learning why dependent events require a new sample space after the first outcome. The one-suit setup keeps the numbers manageable while still showing the core idea clearly.
