Answer:
4 days
Step-by-step explanation:
268-112= 156
156 divided by 39 = 4
1,3,5 because they are all negatives less than -3
-18= you owe 18 dollars
18= you earned 18 dollars
0= you owe nothing/you earned nothing
1. Assume the manufacturer produced 100 products.
2. 70 are acceptable and 30 are defective.
3. the first product has a probability of 70/100 to be selected from the acceptable ones. The second 69/99 (one is removed from the good ones) and the third one 68/98
4. so P(pick 3 consecutive acceptable products)=

=0.339
5. If familiar to the Combination formula C(n, r)=

:
P(picking 3 acceptable out of 100)=n(picking 3 acceptable)/n(picking 3)=C(70, 3)/C(100/3)=

= 0.339
