The probability that no one in the family of 4 will be hospitalized during a year is 0.52
Step-by-step explanation:
The probability for a person to be hospitalized during one year is
![p(h)=0.15](https://tex.z-dn.net/?f=p%28h%29%3D0.15)
As a consequence, the probability for a person of NOT being hospitalized during one year is
![p(h^{-1})=1-0.15=0.85](https://tex.z-dn.net/?f=p%28h%5E%7B-1%7D%29%3D1-0.15%3D0.85)
If we have 4 people in the family, the probability of each of them of NOT being hospitalized during the year is independent from the probability of the others - therefore, these are independent events. This means that the total probability of the 4 people of not being hospitalized during a year is:
![p(h^{-1})^4=(0.85)^4=0.52](https://tex.z-dn.net/?f=p%28h%5E%7B-1%7D%29%5E4%3D%280.85%29%5E4%3D0.52)
So, the probability that no one in the family of 4 will be hospitalized during a year is 0.52.

267 ÷ 3
= 89.
CROSS CHECK!
Lets see if 89 multiplied by 3 would still give us 267.
89 × 3 = 267.
Lets see if 267 divided by 89 would give us 3.
267 ÷ 89 = 3.

Therefore our answer was correct.
To find a missing length when you have an area and another length you divide the area by the known length
23 4/5 divided by 2 4/5= 8 1/2
I think it is 555??
355+200=555
Answer: 30
Step-by-step explanation:
Because you can break the pentagonal base into triangles and the formula to find the area of a triangle is 1/2 Bh so 840/14 = 60 divided by 1/2 = 30
