A.
![\begin{array}{cccccc}x&1&2&3&4&5\\f&0.2&0.3&0.05&0.2&0.25\end{array}](https://tex.z-dn.net/?f=%5Cbegin%7Barray%7D%7Bcccccc%7Dx%261%262%263%264%265%5C%5Cf%260.2%260.3%260.05%260.2%260.25%5Cend%7Barray%7D)
Step-by-step explanation:
First find the sum
![\sum f=4+6+1+4+5=20.](https://tex.z-dn.net/?f=%5Csum%20f%3D4%2B6%2B1%2B4%2B5%3D20.)
Now, find the probabilities:
Hence, the frequency distribution table is
![\begin{array}{cccccc}x&1&2&3&4&5\\f&0.2&0.3&0.05&0.2&0.25\end{array}](https://tex.z-dn.net/?f=%5Cbegin%7Barray%7D%7Bcccccc%7Dx%261%262%263%264%265%5C%5Cf%260.2%260.3%260.05%260.2%260.25%5Cend%7Barray%7D)
Answer:
24
Step-by-step explanation:
If she did all 3of them today then you subtract a day from each one then it would look like this
5+4+15=24
B. 10.1%
(2)(12)($88.18) ÷ [($1100)(18+1)]
(2,116.32) ÷ (20,900)
= 0.1012
= 10.1%
