Given
A committee of 3 members is formed using
5 Admin, 34 teachers, and 4 staff
Favorable outcomes are selecting 3 members as Administrators
total members =5+34+4=43
Probability is given by
![\Rightarrow P=\dfrac{\text{Favorable}}{\text{Total}}](https://tex.z-dn.net/?f=%5CRightarrow%20P%3D%5Cdfrac%7B%5Ctext%7BFavorable%7D%7D%7B%5Ctext%7BTotal%7D%7D)
![\Rightarrow P=\dfrac{^5C_3}{^{43}C_3}=\dfrac{10}{43\times 41\times 7}\\\\\Rightarrow P=\dfrac{10}{12,341}=0.000810](https://tex.z-dn.net/?f=%5CRightarrow%20P%3D%5Cdfrac%7B%5E5C_3%7D%7B%5E%7B43%7DC_3%7D%3D%5Cdfrac%7B10%7D%7B43%5Ctimes%2041%5Ctimes%207%7D%5C%5C%5C%5C%5CRightarrow%20P%3D%5Cdfrac%7B10%7D%7B12%2C341%7D%3D0.000810)
Answer:
75
Step-by-step explanation:
We line up the tens place of 33 and 42 as well as the ones place so that it looks like:
33
+42
--------
Then we add first the ones, which is 3 + 2 for 5. Then we add the tens together, 3 + 4 is 7. We put the five first since its in the ones place and the 7 second since its in the tens place for 75.
