Final answer:

This question involves calculating probabilities for a binomial experiment with n=10 trials and a success probability p=0.10 using either a binomial table or statistical software. The individual probabilities for f(0), f(2), P(x < 3), and P(x ≥ 5) can be computed using functions such as binompdf and binomcdf.

Step-by-step explanation:

The question presented involves a binomial experiment with the number of trials n being 10 and the probability of a success p being 0.10 in each trial. The question asks to use the binomial tables or a calculator to find certain probabilities. Here are the solutions using a binomial distribution:

  • f(0) represents the probability of having zero successes, which can be found using binompdf(10, 0.10, 0).
  • f(2) represents the probability of having exactly two successes, calculated using binompdf(10, 0.10, 2).
  • P(x < 3) represents the probability of having fewer than three successes and is found using the cumulative binomial probability formula binomcdf(10, 0.10, 2).
  • To find P(x ≥ 5), you would need to calculate 1 minus the probability of having fewer than five successes, which is 1 - binomcdf(10, 0.10, 4).

These calculations can be made using a graphing calculator or statistical software capable of computing binomial probabilities. Remember that the binomial distribution is appropriate in this scenario because there are a fixed number of trials, two possible outcomes per trial (success or failure), and the probability of success is the same in each trial.
