Answer:
The probability that exactly three of them are comfortable with delivery by drones is 0.2583.
Step-by-step explanation:
Let <em>X</em> = number of consumers comfortable having drones deliver their purchases.
The probability of the random variable <em>X</em> is, P (X) = <em>p</em> = 0.43.
Then <em>q</em> is, <em>q</em> = 1 - p
A sample of <em>n</em> = 5 consumers are selected.
The random variable <em>X</em> follows a Binomial distribution with parameters <em>n</em> and <em>p</em>.
The pmf of <em>X</em> is:
Compute the value of P (X = 3) as follows:
Thus, the probability that exactly three of them are comfortable with delivery by drones is 0.2583.

Answer:
192 degrees
Step-by-step explanation:
The explanation is really simple. As you should know, the degree measure of a circle is 360 degrees such that the m∠x + the m∠y can be computed as such:
360 - 104 - 64 = m∠x + m∠y
256 - 64 = m∠x + m∠y
m∠x + m∠y = 192 degrees
