A binomial probability experiment is conducted with given parameters. Compute the probability of x successes in the n independen
snow_lady [41]

Answer:

P(X = 4) = 0.1876

Step-by-step explanation:

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

In which C_{n,x} is the number of different combinations of x objects from a set of n elements, given by the following formula.

C_{n,x} = \frac{n!}{x!(n-x)!}

And p is the probability of X happening.

In this question:

n = 15, p = 0.2

We want P(X = 4). So

P(X = 4) = C_{15,4}.(0.2)^{4}.(0.8)^{11} = 0.1876

7nadin3 [17]

Answer:

x=-1

Step-by-step explanation:

1. Remove the parenthesis

   -x + 1 = -4x - 2

2. Get x alone

  -x + 1 = -4x - 2

  +1x        +1x

1=-3x - 2

+2      +2

3=-3x          -3x/-3= x      3/-3 = -1      

x=-1
