Answer:
27.94%
Step-by-step explanation:
The statement tells us that we have 5 red balls and 6 blue balls, that is, there are 11 in total (5 + 6)
So the probability of red balls = 5/11 and blue balls probability = 6/11
Let X be the number of red balls of those 5 selected balls.
Then X follows a binomial distribution with the following parameters:
n = 5
p = 5/11
q = 6/11
P (X) = nCx * p ^ (x) * q ^ (n -x)
required probability is P (X = 3), replacing:
P (X = 3) = 5C3 * (5/11) ^ (3) * (6/11) ^ (5 -3)
P (X = 3) = 5! / (3! (5-3)!) * 0.02794
P (X = 3) = 10 * 0.02794
P (X = 3) = 0.2794
Which means that the probability is 27.94%
Answer:
after one day, 96.8 % are still there
and from this portion will remain 96.8% one day later
so you multiply 0.968 by itself seven times
0,968^7 = 0.7964
<h3>After one week there are 79.64 % left.</h3>
First you need to figure out how many hours he has been working for you, lets say h = 1 then you answer would be both A and B, if it is h = 2 then your answer is C, B, A, and maybe D (Because I am not really sure what D means)
Answer:
4px=20
x=(20/4p)-----(1)
-4px=20--------(2)
putting value of x in epn 2
-4p*20=20*4p
-80p=+80p
Both cut these value are rejected
