to get to know her students better, ms. alexander surveyed her math students to determine what hobbies and school subjects they prefer.\n\n| |athletics|the arts|\n|--|--|--|\n|math|1|2|\n|literature|3|4|\n\nwhat is the probability that a randomly selected student prefers math or prefers athletics?\nsimplify any fractions.
Answer
Explanation:
Step1: Calculate total number of students
$1 + 2+3 + 4=10$
Step2: Calculate number of students who prefer math or athletics
Number of students who prefer math: $1 + 2=3$. Number of students who prefer athletics: $1+3 = 4$. But the student who prefers both math and athletics is counted twice. So number of students who prefer math or athletics is $3+4 - 1=6$
Step3: Calculate the probability
Probability = $\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}=\frac{6}{10}=\frac{3}{5}$
Answer:
$\frac{3}{5}$
