Answer:
a) 13% probability that the first teammate you meet has entensive telecommunications experience.
b) 45% probability that the first teammate you meet has some telecommunications experience.
c) 87% probability that the first teammate you meet has no more than limited telecommunications experience.
Step-by-step explanation:
We have that:
55% have had no experience in the telecommunications industry.
32% have had limited experience
The rest is 100 - (55+32) = 100 - 87 = 13%. So 13% have had extensive experience.
a) Extensive telecommunications experience?
13% probability that the first teammate you meet has entensive telecommunications experience.
b) Some telecommunications experience?
Either limited or extensive experience
32+13 = 45%
45% probability that the first teammate you meet has some telecommunications experience.
c) No more than limited telecommunications experience?
No experience or limited experience.
So
55+32 = 87%
87% probability that the first teammate you meet has no more than limited telecommunications experience.
