Answer:
0.1905 = 19.05%
Step-by-step explanation:
We have a total of 106 containers of oxygen, from which:
20 have oxygen not ionized, 86 have oxygen ionized.
If the first one selected is ionized, now we have 20 not ionized and 85 ionized.
So the probability of the second one selected being not ionized is the number of not ionized (20) over the total number of containers (20 + 85):
P = 20 / (20 + 85) = 0.1905 = 19.05%
The answer is 7/5

Good luck on your assignment
<span>This is a reduction to simplest form problem. You are given 33/36. All you
need to do is to find a divisible number that can be divided to both the numerator
and denominator, 33 and 36 respectively. It’s like finding the GCF or greatest
common factor. The greatest common factor is the factor that divides both
numbers. If you try to divide them by three, 33 divided by 3 gives 11 and 36
divided by 3 gives 12. The simplest form is 11/12. </span>
