Yes he does. If you cut something 6 times you make 7 pieces
I am not for sure but I think 1.13*10-4

Answer:
a) 
b) 
And replacing we got:
![P(X \geq 5) = 1-[0.01+0.02+0.03+0.12+0.11]=1-0.29=0.71](https://tex.z-dn.net/?f=%20P%28X%20%5Cgeq%205%29%20%3D%201-%5B0.01%2B0.02%2B0.03%2B0.12%2B0.11%5D%3D1-0.29%3D0.71)
Step-by-step explanation:
For this case we can solve this problem creating the following table
Number of particles Frequency Rel. Frequency
0 1 1/100 =0.01
1 2 2/100 =0.02
2 3 3/100=0.03
3 12 12/100=0.12
4 11 11/100=0.11
5 15 15/100=0.15
6 18 18/100=0.18
7 10 10/100=0.1
8 12 12/100=0.12
9 4 4/100=0.04
10 5 5/100=0.05
11 3 3/100=0.03
12 1 1/100=0.01
13 2 2/100=0.02
14 1 1/100=0.01
Total 100 1
We assume on this case the the relative frequency represent the probability.
Let X the number of contaminating particles on a silicon wafer
What proportion of the sampled wafers had at least one particle?
For this case we can use the complement rule like this:

At least five particles?
Again for this case we can use the complement rule and we got:

And replacing we got:
![P(X \geq 5) = 1-[0.01+0.02+0.03+0.12+0.11]=1-0.29=0.71](https://tex.z-dn.net/?f=%20P%28X%20%5Cgeq%205%29%20%3D%201-%5B0.01%2B0.02%2B0.03%2B0.12%2B0.11%5D%3D1-0.29%3D0.71)
