Question

Assume that we want to find the probability that when four consumers are randomly​ selected, exactly two of them are comfortable with delivery by drones. Also assume that 33​% of consumers are comfortable with the drones​ (based on a​ survey). Identify the values of​ n, x,​ p, and q.N=X=P=Q=

Answer 1

Answer:

0.293

Step-by-step explanation:

X ~ B (4, 0.33)

n = 4,

p = 0.33,

q = 1 - p = 0.67

x = 2

P(x = 2) = 4C2 × 0.33² × 0.67²

= 0.29331126

= 0.293 (3 sf)
