Answer:

300

Step-by-step explanation:

A number cube has total six possible outcomes:

1, 2, 3, 4, 5 and 6

Probability of the occurrence of each side is: 1/6

From the possible outcomes, the even number are 2,4,6

Therefore the probability of the occurrence of an even number is:

1/6 + 1/6 + 1/6

=> 3/6

=> 1/2

1/2 probability shows that if a number cube is rolled 'n' times, (1/2)*n number of chances are it is an even number.

So the expectation of rolling an even number with 600 trials is:

(1/2)*600

=> 300

The distance formula between the line is:
$\sqrt{{(x1 - x2)}^{2} + {(y1 - y2)}^{2} }$
Thus,the distance of the above:
$\sqrt{ {( - 1 - 4)}^{2} + {(5 - 1)}^{2} } \\ = \sqrt{ { - 5}^{2} + {4}^{2} } \\ = \sqrt{25 + 16 } \\ = \sqrt{41} \\ = 6.4$

The answer is 6.4 units.

Hope it helps!

Solution :

Given that there is only one set which can contain all the five correct answers. While guessing that I am likely to choose only one sequence of the answers as another, then the probability of getting all the five answers correct is given by :

Given : X $\sim$ binomial $\left( 5 , \frac{1}{3} \right)$
