I have these 3 tables and can anyone explain it to me whether each of these tables shows a correct probability distribution? many thanks!
x 1 2 3 4 5
P(x) 0.10 0.20 0.25 0.40 0.05
x 1 2 3 4 5
P(x) 1/10 3/10 1/5 3/10 1/10
x 1 2 3 4 5
P(x) 0.05 -0.30 0.35 0.40 0.50
Hello everyone, I have this probability question but am unsure how to answer questions 1 to 5, can someone help?
A total of 20 applicants came in for a job interview. Among them, four were 45 years old, six were 39 years old, three were 42 years old, five were 40 years old, and two were 35 years old. Let x be the age of a randomly selected applicant.
1. What are the possible values for the random variable?
2. Construct a probability distribution for the given random variable.
3. Construct a histogram for the probability distribution
4. What is the probability that a randomly selected applicant is 35 years old?
5. What is the probability that a randomly selected applicant is older than 43 years old?
