MO MAP Grade 7 Statistics and Probability Practice

Statistics and Probability skills

Use random sampling to draw inferences about a population

Draw informal comparative inferences about two populations

Investigate chance processes and develop, use, and evaluate probability models

Standards basis

Missouri Learning Standards (Mathematics K-5 and Mathematics 6-12; revised standards approved April 19, 2016) — Missouri

How the MO MAP reports it

Missouri’s MAP math is built from the Missouri Learning Standards and the state’s item specifications, not from a separate national testing framework. The standards are closely CCSS-aligned in structure, with grade-level and course-level domains used as the native reporting/coverage structure.

Blueprint & weighting

Missouri publishes grade-level and EOC blueprints, but the accessible official pages in this pass did not expose the domain-by-domain percentage tables. The assessment page states that item specifications organize expectations by domains/strands and that blueprints are available for grade-level and EOC assessments.

Mia can pick from $5$ shirts and $2$ hats. How many different (shirt, hat) outfits are possible?

By the counting principle: $5 \times 2 = 10$ .

A jar contains $5$ red tokens and $7$ blue tokens. One token is chosen at random. What is the probability that the token is red?

There are $5 + 7 = 12$ tokens in all and $5$ are red, so $P(\text{red}) = \dfrac{5}{12}$ .

One letter is chosen at random from the word GAMES. What is the probability the letter is a vowel?

GAMES has $5$ letters, and $2$ of them ( $A$ and $E$ ) are vowels, so $P = \dfrac{2}{5}$ .

The whole numbers $1$ through $24$ were each written on separate cards. Those $24$ cards were placed in a bag. One card will be randomly drawn from this bag. What is the probability that the card will show a number divisible by $4$ ?

Multiples of $4$ from $1$ to $24$ are $4, 8, 12, 16, 20, 24$ , so there are $6$ favorable outcomes: $P = \tfrac{6}{24} = \tfrac{1}{4}$ .

A bag holds $4$ red marbles and $5$ green marbles. One marble is drawn at random. What is the probability it is green? Give a simplified fraction.

There are $4 + 5 = 9$ marbles in all and $5$ are green, so $P(\text{green}) = \dfrac{5}{9}$ .

In a random sample of 40, 12 were red marbles. Estimate how many of 200 are red in the whole population.

Proportion $= \dfrac{12}{40}$ . Estimate $= \dfrac{12}{40} \times 200 = 60$ .

Spinner A has $5$ equal sections and exactly $1$ section is gold. Spinner B has $4$ equal sections and exactly $1$ section is gold. Each spinner is spun once. What is the probability that both spinners land on gold?

$P(\text{gold on A}) = \dfrac{1}{5}$ and $P(\text{gold on B}) = \dfrac{1}{4}$ . So $P(\text{both gold}) = \dfrac{1}{5} \times \dfrac{1}{4} = \dfrac{1}{20}$ .

For two independent events, the probability of a head then a 4: $P(A)=\tfrac{1}{2}$ , $P(B)=\tfrac{1}{6}$ . Find $P(A \text{ and } B)$ as a simplified fraction.
