Answer:

a) S = (CR, MR and MC) = 3

b) 1/3

c) 2/3

d)1/3

Step-by-step explanation:

a) Let Clarice be 'C', Marco be 'M' and Roberto be 'R'

Since two employees will be selected at random, the sample space will be S = (CR, MR and MC) i.e 3C2 by rule of combination.

b) For probability that Maurice and Clarice attend the conference.

Probability =number of required outcome/total outcome

Required outcome = 1 since MC occurs once in the sample space.

Total outcome = 3 (total number of sample space).

Probability that Maurice and Clarice attend the conference= 1/3

c) Probability that Marco attends the conference will be 2/3 since Marco occur twice in the sample space.

d) Probability that Roberto stays home will be 1/3 since Roberto occurs twice in the sample space i.e (1-2/3)
