Sample: the first question, solved
A bag has 2 red and 8 blue marbles. What fraction represents the probability of drawing red?
📘 Worked solution
✓There are 2 red marbles out of 10 total, so the probability is 2/10, which simplifies to 1/5.
And one from the hard end
A basketball shot's success probability changes from 1/10 to 3/4 over time (improving with practice). Place both on a probability line and describe the shift.
