Answer:
0.1728
Step-by-step explanation:
We know that the random variable, X, arises from a binomial experiment, besides n = 14 and p = 0.13, so, q = 1 - p = 1 - 0.13 = 0.87. For a particular value x, we can compute the probability P(X = x) as , therefore,
. You can copy and paste the next instruction in excel to find the answer =COMBIN(14, 3)*0.13^3*0.87^11

Answer:
Step-by-step explanation:
Given expression:
Replace 900 with 30² :
(We need to use the absolute value of √x² since the x term was originally to the power of 2, which means the value of x² is always positive since the exponent is even).
Simplify:
(We need to use the absolute value of z³ since the z term was original to the power of 6, which means the value of z⁶ is always positive since the exponent is even).
