A calculator is able to generate random numbers from the interval (0, 1). We need five random numbers from (0, 2/5). Using this calculator, how many independent random numbers should we generate, on average, to find the five numbers needed?

12.5

Step-by-step explanation:

Using the negative binomial method, we can solve this question. Try defining the variable with parameters (r,p) with success probability p.

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.

step-by-step explanation:

m = 2e

m = 2 so 2 = 2e

1 = e
