Calculating the Probability of Volodya Receiving a Puzzle with Cars

To calculate the probability of Volodya receiving a puzzle with cars, we can use the following formula:

Probability (P) = Number of favorable outcomes / Total number of possible outcomes

In this case, the number of favorable outcomes is the number of puzzles with cars, and the total number of possible outcomes is the total number of puzzles.

Given Information

- The Parent Committee purchased 20 puzzles for the children, with 14 of them featuring cars and 6 featuring city views. - The puzzles are distributed randomly among 20 children.

Calculation

- Number of puzzles with cars: 14 - Total number of puzzles: 20 - Number of children: 20

Probability Calculation

Probability (P) = 14 / 20

Probability (P) = 0.7

So, the probability of Volodya receiving a puzzle with cars is 0.7 or 70%.
