<u>Short answer</u> = C) 8/10
<u>Working :</u>
Tan A = 8/6 = Opposite / AdjacentOpposite = 8 units
Adjacent = 6 units
Hypotenuse =
=
=
= 10 units
Cos B = Adjacent/ Hypotenuse
∴ cos B= 8/10
Simplify this expression 3u/14u

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.
