3.1 Exercise 5

Avg difficulty 2.5

the table describes the distribution of a random sample S of 100 individuals, organized by sex assigned at birth and whether they are right- or left-handed.

Right-handed Left-handed
Males 43 9
Females 44 4

Let’s denote the events M = the subject is male, F = the subject is female, R = the subject is right-handed, L = the subject is left-handed. Compute the following probabilities:

  1. P(M)
  2. P(F)
  3. P(R)
  4. P(L)
  5. P(M ∩\cap R)
  6. P(F ∩\cap L)
  7. P(M ∪\cup F)
  8. P(M ∪\cup R)
  9. P(F ∪\cup L)
  10. P(M')
  11. P(R|\left|\right.M)
  12. P(F|\left|\right.L)
  13. P(L|\left|\right.F)
