Answer:
0.4444
Step-by-step explanation:
Use the following property to ease the calculation:
P(At least one)=1-P(None)
Total number of electrical components: 9
Number that does not function well :1
Number that functions well : 8
We have
ways to to choose 4 good components from 8.
We have
ways to choose 4 components from a total of 9.
If all function properly then none is bad, we
way to do this.
P(At least one)=
P(At least one)=
P(At least one)=0.4444
Answer: yes
Step-by-step explanation:
S = 2 (lw + lh + hw)
S = 2 ((8.5)(11) + (8.5)(2) + (11)(2))
S = 2 (93.5 + 17 + 22)
S = 2 (132.5)
S = 265 sq in
