Answer:
a)S= (1,2,3,4,5,6)
b) 1/6 or 16.67%
c) 1/3 or 33.33%
d) 5/6 or 83.33%
Step-by-step explanation:
a) Sample space is the list of all the possible sample in this its either tool 1,2,3,4,5 or 6
b) probability of selecting from tool 1 is equally likely to picking from any cutting tool therefore it
1/6 or 16.7%
c) probability of selecting from any tool is 16.7% so probability of selecting from 3 or 5 = 16.67% + 16.67% = 33.3%
d) if the part is not from tool 4 then its from tool 1, or tool 2 or tool 3 or tool 5 or tool 6 therefore its
1/6+1/6+1/6+1/6+1/6 = 5/6 or 8.33%

Step-by-step explanation:
Answer:
3(3b +4)
Step-by-step explanation:
The greatest common factor (GCF) of 9 and 12 is 3, so you're being asked to factor that out.
9b +12 = 3(3b +4)
_____
The GCF can be found a couple of ways. One of them is to list the prime factors and identify those that are common.
9b = 3 × 3 × b
12 = 2 × 2 × 3
For these two terms, the only common factor is 3.
