Answer:

Gordan is the eldest and he is 34.

Step-by-step explanation:

Well let Krutica’s age = x

K = x

G = x+5

D = x-6

K+G+D = 86

x + x+5 + x-6 = 86

3x - 1 = 86

3x = 87

x = 29

Gordon is the oldest so G = 29+5

G = 34

D.) 15/6

- 3 times 52 = 156, and since you can't exactly convert it to a fraction then i'm assuming that it is 'D'.

Answer:

P(X > 0) = 0.9222

Step-by-step explanation:

For each name, there are only two outcomes. Either the name is authentic, or it is not. So, we can solve this problem using the binomial probability distribution.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

P(X = x) = C_{n,x}.\pi^{x}.(1-\pi)^{n-x}

In which C_{n,x} is the number of different combinatios of x objects from a set of n elements, given by the following formula.

C_{n,x} = \frac{n!}{x!(n-x)!}

And \pi is the probability of X happening.

In this problem.

5 names are selected, so n = 5

A success is a name being non-authentic. 40% of the names are non-authentic, so \pi = 0.40.

We have to find P(X > 0)

Either the number of non-authentic names is 0, or is greater than 0. The sum of these probabilities is decimal 1. So:

P(X = 0) + P(X > 0) = 1

P(X > 0) = 1 - P(X = 0)

P(X = x) = C_{n,x}.\pi^{x}.(1-\pi)^{n-x}

P(X = 0) = C_{5,0}*(0.40)^{0}*(0.6)^{5} = 0.0778

So

P(X > 0) = 1 - P(X = 0) = 1-0.0778 = 0.9222
