of the trains that recently pulled into westford station, 16 were full and 4 had room for more passengers. what is the experimental probability that the next train to pull in will be full? simplify your answer and write it as a fraction or whole number. p(full) =
Answer
Explanation:
Step1: Find total number of trains
The total number of trains is the sum of full - trains and trains with room. So, $16 + 4=20$.
Step2: Calculate experimental probability
The experimental probability $P(\text{full})$ of a train being full is the number of full trains divided by the total number of trains. So, $P(\text{full})=\frac{16}{20}$.
Step3: Simplify the fraction
We simplify $\frac{16}{20}$ by dividing both the numerator and denominator by their greatest common divisor, which is 4. $\frac{16\div4}{20\div4}=\frac{4}{5}$.
Answer:
$\frac{4}{5}$
