Question

For the probability experiment of selecting a chip at random from a bag

of 100 numbered chips, numbered 1-100. Calculate the probability of
selecting a number less than 10. Explain your thinking.

Answer 1

9/100

The chance of selecting a chip at random is equal for all chips, and since there are 9 chips that have a number less than 9, you add their individual probabilities so that 1/100 + 1/100 + 1/100... = 9/100
