Students can expect to face FOUR conceptually similar probability questions on the CAHSEE assessing three different Grade-6 standards (6PS3.1, 6PS3.3, 6PS3.5).
Released items suggest at least one probability problem using a diagram, like a spinner or chart, in which students must count of the total possible outcomes and the use that for the denominator, and the then count the total favorable outcomes and use that for the numerator.
As outlined in the exam blueprint, there are four key understandings from this topic:
• know that probabilities are ratios that can be expressed as fractions, decimals, or percentages.
• compute the probability of a described event.
• verify the reasonableness of a computed probability.
• compute the probability that an event will not occur.
