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? write your answer as a fraction or whole number. p(full) =
Answer
Explanation:
Step1: Calculate total number of trains
$16 + 4=20$
Step2: Calculate experimental - probability
The experimental probability $P(\text{full})$ is the number of full - trains divided by the total number of trains. So $P(\text{full})=\frac{16}{20}$
Step3: Simplify the fraction
$\frac{16}{20}=\frac{4}{5}$
Answer:
$\frac{4}{5}$
