Answer:0.2

Step-by-step explanation: Let the two companies be A and B

Pa = probability of getting a job offer from only company A

Pb = probability of getting a job offer from only company B

Pbb = probability of getting a job offer from both companies

Pn = ProbabityProbability of getting a job from neither companies

The relation could be combined using:

Pbb+Pa+Pb+Pn=1

Pn = 0.3

(Pa + Pb) = probability of offer from exactly one of A or B = 0.5

Pbb + 0.5 + 0.3 = 1

Pbb+0.8=1

Pbb=1-0.8

Pbb = 0.2
