Answer:
Step-by-step explanation:
odd numbers are 1,3,5,7
number of odd cards=4
Total number of cards=8
Number of cards less than 4=3 {1,2,3}

Answer:
The answers are a. 0.27 b. 0.2 c. 0.2 d. 0.3 e. 0.3 f. 1
Step-by-step explanation:
Total output = 100% = 1
Total defective = 6% + 5% + 8% + 8% = 27% = 27
a. Prob of defective item = total defective/total output
= 27/100
= 0.27
b. Prob of defective from machine 1 = 6/27 =0.2222
~ 0.2
c. Prob of item defective from machine2 = 5/27 = 0.1852
~0.2
d. Prob of de defective from machine 3 = 8/27 = 0.2963
~0.3
e. Prob of defective from machine 4
= 8/27 = 0.2963
~ 0.3
f. Sum of prob from b-e
0.2 + 0.2 + 0.3 + 0.3
= 1
(4 / 5) * (20 hours) = 16 hours
"total" means "sum" more or less, so the total of m and 10 is m+10
The square of this is (m+10)^2
----------------------
If you want to expand this out, then you would get
(m+10)^2 = (m+10)(m+10)
(m+10)^2 = A(m+10) ... let A = m+10
(m+10)^2 = A*m + A*10
(m+10)^2 = m(A) + 10(A)
(m+10)^2 = m(m+10) + 10(m+10) .... plug in A = m+10
(m+10)^2 = m^2+10m+10m+100
(m+10)^2 = m^2+20m+100
