a class takes a field trip to a carnival. 11 students do face painting, 6 students play ski ball, 9 students play cornhole, and 4 students play darts. find the probability that a student did not do face painting. p(not face painting) = ? round your answer to the nearest hundredth.
Answer
Answer:
0.63
Explanation:
Step1: Calculate total number of students
$11 + 6+9 + 4=30$
Step2: Calculate number of students not doing face - painting
$30-11 = 19$
Step3: Calculate the probability
$P(\text{Not Face Painting})=\frac{19}{30}\approx0.63$
