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

kipiarov [429]

Answer:

  11.2 ft

Step-by-step explanation:

Assuming the building meets the ground at right angles, the right triangle formed has side length 10 ft and hypotenuse 15 ft. Then the other side length (d) is given by the Pythagorean theorem as ...

  d² + 10² = 15²

  d² = 225 -100 = 125

  d = √125 = 5√5 ≈ 11.2 . . . feet

The bottom of the ladder is about 11.2 feet from the building
