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.
The answer is 4. The mean is 4 beacuse thats what you multiply ... and yeah
Ans = 2 move 8x to other side and 4 to other side
Answer:
100 sir
Step-by-step explanation:
10 times 5 is 50 and plus 50 is 100
Answer:
B) 24/35
Step-by-step explanation:
Cos(X)= Adjacent/Hypotenuse
Cos(X) = 24/25
Therefore, option B is your answer.
Hope this answers your question!!
