Answer:
The score is
Step-by-step explanation:
From the question we are told that
The population mean is
The standard deviation is
From the question we are told that the score follow a normal distribution
i.e
The proportion of score in the top 10% is mathematically
Where x is the minimum score required to be in the top 10%
Now the
So
So
So the critical value of 0.10 from the normal distribution table is
So
Answer:
The probability of one or more catastrophes in:
(1) Two mission is 0.0166.
(2) Five mission is 0.0410.
(3) Ten mission is 0.0803.
(4) Fifty mission is 0.3419.
Step-by-step explanation:
Let <em>X</em> = number of catastrophes in the missions.
The probability of a catastrophe in a mission is, P (X) = .
The random variable <em>X</em> follows a Binomial distribution with parameters <em>n</em> and <em>p</em>.
The probability mass function of <em>X </em>is:
In this case we need to compute the probability of 1 or more than 1 catastrophes in <em>n</em> missions.
Then the value of P (X ≥ 1) is:
P (X ≥ 1) = 1 - P (X < 1)
= 1 - P (X = 0)
