Step-by-step explanation:
<u><em>Step(i)</em></u>:-
Let 'X' be the random variable in Poisson distribution
<em>Mean of the Poisson distribution λ or ∝ = 3 per (cm³)</em>
Given n = 5 samples
<u><em>Step(ii):-</em></u>
<em>The probability that at least one sample will contain one or more bacterial colonies</em>
<em>P(X≥1) = 1-P(X< 1) </em>
<em> = 1 - P( X=0)</em>

Answer:
Step-by-step explanation:
Do you mean 3/7x or 3/(7x) ?
If 3/7x = 33 then x = 33·7/3 = 77
If 3/(7x) = 33 then x = 1/77
Answer:
<h2>x = 4</h2>
Step-by-step explanation:
A line with undefined slope is a vertical line.
An equation of a vertical line: x = a (a - real number).
Each point on a line x = a has coordinates (a, b) (b - any real number).
We have the point (4, 0) → x = 4
I think it's 1/6. Because before school she drinks 1/4 then before lunch she drink 2/3 if 1/4 so you would multiply. 1*2=2. 4*3=12. So you get 2/12 or if you simplify, 1/6
