Suppose that start-up companies in the area of biotechnology have probability 0.2 of becoming profitable, and that those in the

schepotkina [342]

Answer:

a) 0.03

b) 0.68

c) 0.32

Step-by-step explanation:

We are given the following in the question:

B: companies in the area of biotechnology

I: companies in the area of information technology

P(B) = 0.2

P(I) = 0.15

The two events are given to be independent.

a) P(both companies become profitable)

$P(B\cap I) = P(B)\times P(I)\\= 0.2\times 0.15 = 0.03$

0.03 is the probability that both companies become profitable

b) P(neither company becomes profitable)

$P(B'\cap I')\\=P(B')\times P(I')\\=(1-P(B))(1-P(I))\\=(1-0.2)(1-0.15)\\=0.68$

0.68 is the probability that neither company becomes profitable.

c) P(at least one of the two companies become profitable)

$P(B\cup I) = P(B) + P(I) - P(B\cap I)\\= 0.2 + 0.15 - 0.03\\=0.32$

0.32 is the probability that at least one of the two companies become profitable
