Two fair dice are tossed, and the up face on each die is recorded. Find the probability of observing each of the following event

Paladinen [302]

Answer:

Step-by-step explanation:

The sample space is shown in the attached photo.

Probability = number of favourable outcomes/total number of outcomes.

Looking at the diagram, the total possible outcomes is 36.

A) from the diagram, the total number of events in which the sum of the numbers is odd is 18. Therefore, the probability that the sum of the numbers is odd is

18/36 = 1/2

B) the total number of events in which the sum of the numbers is 10 or more is 6. Therefore, the probability that the sum of the numbers is 10 or more is

6/36 = 1/6

C) the total number of events in which 3 appears on each of the two dice is 1. Therefore, the probability that 3 appears on each of the two dice is

1/36

MATCH EACH EQUATION WITH THE DESCRIPTION OF ITS GRAPH BELOW A. Y= - 10x B. Y = 2.5x -7

yulyashka [42]

Answer:

A. y = -10x

Step-by-step explanation:

An equation that has a line that passes through the origin (0, 0) is represented in slope intercept form as y = mx

Where, m is the slope.

Therefore,

The equation that represents a graph with a negative slope and passes through the origin would be:

y = -10x

-10 is the slope (m).

find the odds in favor of drawing a red marble whyen a marble is selected at random from a bag containing 2 yellow, 5 red and 6

bearhunter [10]

Answer:

The odd in favor of drawing a red marble is 5:8

Step-by-step explanation:

Let’s calculate the probability of selecting a red marble

That would be;

number of red marbles/Total number of marbles

Total number of marbles = 2 + 5 + 6 = 13

So the probability of drawing a red marble is 5/13

The probability of not drawing a red marble = 1-5/13 = 8/13

So the odd in favor of drawing a red marble is 5:8
