Find the probability that a randomly chosen student is a male or has full-time employment?
Answers
Answer:
Find the probability that a randomly chos student is either a male or has full-time employment = [ total male students and female stdents who are employes only] /[total number of students]. REQUIRED PROBABILITY = 16/31.
The probability that a student randomly choose is a male or a full time employee is 16/31 .
the list for the given data is
male female total
full time 7 3 10
part time 19 24 43
unemployed 3 6 9
employed 29 33 62
total number of male = 7+19+3+29= 58
total number of females = 3+ 24+ 6+ 33=66
total member = 124
probability of being a male chosen randomly =
total male / total member=
58/124
The total full time working student = 7+3 = 10
Total employed student = 29 + 33 = 62
so, total working male student with fulltime employment is
using conditional probability
P(A|B) = P(B|A) P(A) / P(B)
taking condition to be male , full time employed the probability to choose 16/31 .
