The probability of finding 2 never married
10c2*0.4^2*0.6^8=
the probability of finding 1 never married
10C1*0.4*0.6^9=
the probability of finding 0 never married
10C0*0.6^10=
the answer is all the above answers added together.
think you can do the rest of the calculation by yourself. :)
btw nCr=n!/(n-r)!r!
good luck
Answer:
(A)24 square units
(C)72 square units
(D)96 square units
Step-by-step explanation:
<u>Triangular face</u>
Height of the Triangle=6 Units
Base of the Triangle=8 Units
Area of the Triangular Face
![=\frac{1}{2}bh\\ =\frac{1}{2}*8*6\\=24 $ square units](https://tex.z-dn.net/?f=%3D%5Cfrac%7B1%7D%7B2%7Dbh%5C%5C%20%3D%5Cfrac%7B1%7D%7B2%7D%2A8%2A6%5C%5C%3D24%20%24%20square%20units)
<u>Rectangular Faces</u>
Area of Rectangular face with dimension 12 by 10=12 x 10=120 Square Units
Area of Rectangular face with dimension 12 by 8= 12 X 8=96 Square Units
Area of Rectangular face with dimension 12 X 6=12 x 6=72 Square Units
From the options, the areas are:
- 24 square units
- 72 square units
- 96 square units
Answer:
I think it would be -0.416 but I'm not real sure so make sure before using my answer! :3 Have a great day!
