Find the probability of an event by counting favorable outcomes out of all possible outcomes. Read a spinner or die and list the possible outcomes in the sample space. Compare which event is more likely, less likely, or equally likely based on the numbers of outcomes. Use pictures or arrays of objects to calculate the chance of picking a certain item at random.
7sp5
Figure out the chance of drawing a certain color of candy from a bag. Compare different candy colors to decide which outcome is most likely and least likely.
7sp5
Look at a spinner and decide which value is most likely to be landed on. Look at a spinner and decide which value is least likely to be landed on. Tell when two or more outcomes are equally likely by comparing the sizes or counts of sections. Match probability words like most likely, least likely, and equally likely to what the spinner shows.
7sp5
Count how many equal sections are on a spinner and how many match a given number. Convert a probability into a percent chance.
7sp5
Describe the likelihood of an event using the words impossible, unlikely, equally likely, likely, and certain. Compare the number of favorable outcomes to the total outcomes to judge likelihood. Recognize events with probability 0 (impossible) and 1 (certain).
7sp6
Predict how many times an outcome should occur from its theoretical probability. Multiply the number of trials by the probability of the event. Work with probabilities given as fractions, ratios, and percents.
7sp6
Calculate experimental probability from recorded results. Write probabilities as fractions in simplest form. Use experimental results to predict future outcomes when actual probabilities are unknown.
7sp5
Decide whether an outcome is certain, impossible, equally likely, more likely or less likely Recognize that a color not listed in the table is impossible to pick Compare two counts to judge which outcome is more likely Judge whether a likelihood statement is true rather than simply naming a chance
7sp5
Read a probability from a picture of a spinner. Decide which sections satisfy a condition before counting them. Describe a probability using the five likelihood words.
7sp5
Write a probability as a fraction of the whole. Place a probability on a line from impossible to certain. Recognize that impossible is zero and certain is one.
7sp6
Work out the expected results for several known probabilities. Compare a set of results with each one. Choose the probability the results fit best.
7sp6
Work out an expected number of results from a known probability. Count results recorded as tally marks. Put the expected number and the actual number side by side.
7sp5
Test several events against one likelihood word. Work out a probability from a coin, a number cube, a spinner or a bag. Tell certain from likely and impossible from unlikely.
7sp6
Work out how many times an outcome should happen. Read how many times it actually happened. Say whether the results came out above or below the known probability.
