Let X be the number of successes in 6 independent trials of a binomial experiment. The probability of success is 80%. What is the probability that between two and 4 trials (inclusive) are successful?
Added by Spencer V.
Step 1
The probability of success (p) is 80% or 0.8, and the probability of failure (q) is 1 - 0.8 = 0.2. We need to find the probability that between 2 and 4 trials (inclusive) are successful. Show more…

The probability of success on a single trial of a binomial experiment is known to be $\frac{1}{4} .$ The random variable $x$, number of successes, has a mean value of $80 .$ Find the number of trials involved in this experiment and the standard deviation of $x.$
