Assume a binomial probability distribution withn=50 and I = .25. Compute the following: a. The mean and standard deviation of the random variable. b. The probability that x is 15 or more. c. The probability that x is 10 or less.

14

step-by-step explanation:

14 x 3 = 42

let's fu(!

step-by-step explanation:

an = 22 + (n-1) *6

110 seats

step-by-step explanation:

an=a1+(n-1)(d)

a1 = 22   this is the first item in the sequence

d =6   this is how the sequence goes up

a)   an = 22 + (n-1) *6

b) a12 = 22 + (12-1) *6

    a12 = 22+11*6

  a12 = 22 +88

  a12 = 110

step by step explanation: when u removing the parentheses and combined them that would be : x+3y-x-y=2y
