If X is binomial variant with mean 4 and variance 2 find p(x>=3) also find variance of (3X-5)
Added by Brianna R.
Step 1
If \( X \) is a binomial random variable with parameters \( n \) (number of trials) and \( p \) (probability of success), then the mean \( \mu \) and variance \( \sigma^2 \) are given by: \[ \mu = np \] \[ \sigma^2 = np(1-p) \] Show more…
