Answer:
Option (A) 0.40951
Step-by-step explanation:
We are given the following information in the question:
P(target) = 0.90
Let the random variable X represent the number of times he hits ring of the target with a shot of the arrow.
The probability distribution of X is
x: 0 1 2 3 4 5
P(x): 0.00001 0.00045 0.00810 0.07290 0.32805 0.59049
The mean of discrete probability distribution is given by:

Now, we have to evaluate

Option (A) 0.40951 t is the probability that the number of times Luke will hit the inner ring of the target out of the 5 attempts is less than the mean of X.

Answer:
7.31 and 0.685
Step-by-step explanation:
x^2 -8x +5 = 0
use the quadratic formula
- (-8) + √(-8^2 -4(1)(5) / 2(1(
(8 + √(64 -20))/2
(8+√44)/2
8+6.63 / 2
14.63/2= 7.31
+7.31
(8- √44)/2 = 0.685
