Answer:
The required probability is 0.55404.
Step-by-step explanation:
Consider the provided information.
The number of typographical errors on a page of the first booklet is a Poisson random variable with mean 0.2. The number of typographical errors on a page of second booklet is a Poisson random variable with mean 0.3.
Average error for 7 pages booklet and 5 pages booklet series is:
λ = 0.2×7 + 0.3×5 = 2.9
According to Poisson distribution: 
Where
is average number of events.
The probability of more than 2 typographical errors in the two booklets in total is:

Substitute the respective values in the above formula.



Hence, the required probability is 0.55404.
13092.50 Canadian dollars equals to $10000 US dollars.
Answer:
The value of the x is 1/9.
Step-by-step explanation:
Data provided in the question is:

To find out:-
the value of x.
Solution for the equation:-

On solving the given question or equation by using mathematics of algebra we find out the value of x to be 1/9.
8x+5= 69
Move +5 to the other. Sign changes from +5 to -5.
8x+5-5= 69-5
8x= 64
Divide by 8
8x/8= 64/8
x= 8
Answer : x= 8
