Full solution

Q. Ted bought a collection of sports trading cards from a flea market. He randomly picks one card from the collection, puts it back, and picks another card. He repeats this several times and gets

7

baseball,

6

football,

3

soccer, and

4

hockey cards.

\newline

Based on the data, what is the probability that the next card Ted picks will be a baseball card?

\newline

Write your answer as a fraction or whole number.

Count Total Cards: Step $1$ : Count the total number of cards Ted picked. $\newline$ He picked $7$ baseball, $6$ football, $3$ soccer, and $4$ hockey cards. $\newline$ Total cards = $7 + 6 + 3 + 4 = 20$ cards.
Identify Baseball Cards: Step $2$ : Identify the number of baseball cards picked. $\newline$ Baseball cards picked = $7$ .
Calculate Probability: Step $3$ : Calculate the probability of picking a baseball card. $\newline$ Probability = Number of baseball cards / Total number of cards $\newline$ Probability = $\frac{7}{20}$ .
