The most probable value to roll on two dice is 7. The most probable number of heads in two coin flips is one head. Can you think

of most probable values of random events?

a completely random singular event will have no most probable event, but when multiple trials can exist we can find all of the possible values to see which ones occur the most. for example, three dice rolls have the most common events of <span>rolling a 10 or <span>11, because they happen 27 out of 216 possible rolls each or 12.5 percent. Many "most probably events" can be represented as the mean on a standard bell curve.</span></span>

What is meant by the term observed frequencies (O)?
cestrela7 [59]

Answer:

  • The term observed frequencies are found in the sample.

Hence, option 'd' is correct.

Step-by-step explanation:

Unlike the expected frequency which is obtained based on prediction, the observed frequency is the actual frequency that is determined from the experiment.

Therefore, we conclude that

  • The term observed frequencies are found in the sample.

Hence, option 'd' is correct.

Consider isosceles ΔXYZ.
Rom4ik [11]

A triangle is a three-edged polygon with three vertices. It is a fundamental form in geometry. The length of the legs XY and YZ is equal to 39 units.

<h3>What is a triangle?</h3>

A triangle is a three-edged polygon with three vertices. It is a fundamental form in geometry. The sum of all the angles of a triangle is always equal to 180°. An isosceles triangle has two sides out of three equal.

A.) The value of n can be found by equating XY and XZ together,

XY = XZ

9n + 12 = 15n - 6

12 + 6 = 15n - 9n

18 = 6n

n = 3

Hence, the value of n is 3.

The length of different legs of the triangle is,

B.) XY = 9n + 12 = 9(3) + 12 = 27 + 12 = 39

C.) YZ = 15n - 6 = 15(3) - 6 = 45 - 6 = 39

Hence, the length of the legs XY and YZ is equal to 39 units.
