Final answer:
To calculate binomial probabilities, use the binomcdf function on a calculator.
Step-by-step explanation:
To calculate binomial probabilities using the binomial formula or technology, we use the binomcdf function on a calculator. For the given values, a) n = 5, p = 0.79, and P(X < 5), we can use binomcdf(5, 0.79, 4) to find the probability. b) For n = 10, p = 0.33, and P(X > 10), we can subtract the value of binomcdf(10, 0.33, 10) from 1 to find the probability.
