Final answer:
The probability of choosing a remote control car from the box is 1/3, which is calculated by dividing the number of remote control cars (5) by the total number of toys (15).
Step-by-step explanation:
To find the probability of choosing a control car from the box, we use the formula for probability, which is:
Probability = Number of favorable outcomes / Total number of possible outcomes
The number of favorable outcomes is the quantity of remote control cars which is 5. The total number of toys is the sum of all the toys, which are 4 Lego sets + 6 video games + 5 remote control cars = 15 toys in total.
The probability is therefore calculated as:
Probability of choosing a remote control car = 5 (number of remote control cars) / 15 (total number of toys) = 1/3
Hence, the correct answer is C. 1/3.
