Answer: 0.01708
Step-by-step explanation:
Given : If records indicate that 15 houses out of 1000 are expected to be damaged by fire in any year.
i.e. the probability that house damaged buy fire in a year : ![p=\dfrac{15}{1000}=0.015](https://tex.z-dn.net/?f=p%3D%5Cdfrac%7B15%7D%7B1000%7D%3D0.015)
The formula for binomial distribution is given by :-
![^{n}C_xp^x(1-p)^{n-x}](https://tex.z-dn.net/?f=%5E%7Bn%7DC_xp%5Ex%281-p%29%5E%7Bn-x%7D)
Now, the probability that a woman who owns 14 houses will have fire damage in 2 of them in a year (put n=14 and x=2), we get
![^{14}C_2(0.015)^2(1-0.015)^{14-2}\\\\=\dfrac{14!}{2!(14-2)!}(0.015)^2(0.985)^{12}\\\\=0.0170788520518\approx0.01708](https://tex.z-dn.net/?f=%5E%7B14%7DC_2%280.015%29%5E2%281-0.015%29%5E%7B14-2%7D%5C%5C%5C%5C%3D%5Cdfrac%7B14%21%7D%7B2%21%2814-2%29%21%7D%280.015%29%5E2%280.985%29%5E%7B12%7D%5C%5C%5C%5C%3D0.0170788520518%5Capprox0.01708)
Hence, the required probability = 0.01708
Ok so you would find the area of all of the shapes and then add it together. to find the area of the square you would multiply 8 by 8 to get 64. Then you would go on to finding the area of the four triangles which can be found by multiplying the base times the height to get 48. after you do this you would divide 48 by two to get 24 which is your area for the triangles. since there are four triangles you would multiply 24 by 4 to get 96. Finally to get the surface area you add 96 with 64 to get your surface area which is 160 in^2
