The weight of 1000 samples is 10 pounds

\bf \begin{array}{ccll}
samples&lbs\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
10&0.1\\
1000&x
\end{array}\implies \cfrac{10}{1000}=\cfrac{0.1}{x}\implies x=\cfrac{1000\cdot 0.1}{10}

you could also look at it this way, 1000 samples is really 10 * 100, or 100 times 10, if 10 weight 0.1, then 100 times that will just be 100 * 0.1.

Let x be the number of successes throughout n independent repetitions of a random experiment having probability of success p=1/4
Llana [10]

To answer problems like this you have to use binomial:

P (x > 1) = 1 – p (0 < x < 1) > .7 

So:

1 – p (0) – p (1) > .7 

1 – (3/ 4) ^n – (3/ 4) ^n (n – 1 ) (1/ 4) > .7 

Therefore n > 5.185, and the smallest value of n so that we can satisfy the given condition is 6 (rounded up)
