It’s 0.0081 HOPE THIs helps
No.
1/4 would be proportional to 9/36.
8/36 can be simplified to 4/18, and further reduced to 2/9.
50.75
you multiply 14.50 times 3.5
the reason why it is 3.5 is because there are two half hours in one hour, and another half hour plus 15 minutes ( which is half of a half hour)
i hope this is clear!!
good luck!!
Wouldnt it be 21 idk dont pay attention to me lol
Answer: ![\dfrac{1}{220}](https://tex.z-dn.net/?f=%5Cdfrac%7B1%7D%7B220%7D)
Step-by-step explanation:
Given
There are 3 marbles of red, blue, green and orange
Total marbles are 12
No of ways of choosing 3 green marbles out of 3 green marbles is ![^3C_3](https://tex.z-dn.net/?f=%5E3C_3)
Total no of ways of selecting 3 marbles out of 12 are ![^{12}C_3](https://tex.z-dn.net/?f=%5E%7B12%7DC_3)
So, the probability is
![\Rightarrow P=\dfrac{^3C_3}{^{12}C_3}=\dfrac{1\times 3\times 2\times 1}{12\times 11\times 10}\\\\\Rightarrow P=\dfrac{1}{220}](https://tex.z-dn.net/?f=%5CRightarrow%20P%3D%5Cdfrac%7B%5E3C_3%7D%7B%5E%7B12%7DC_3%7D%3D%5Cdfrac%7B1%5Ctimes%203%5Ctimes%202%5Ctimes%201%7D%7B12%5Ctimes%2011%5Ctimes%2010%7D%5C%5C%5C%5C%5CRightarrow%20P%3D%5Cdfrac%7B1%7D%7B220%7D)
