Renee is playing a game with marbles and a spinner. the spinner has four sections: orange, black, purple, and white. the marbles are kept in a bag and come in three colors: orange, black, and purple. renee first spins the spinner and then picks a marble from the bag without looking. what is the probability that the color of the marble matches the color on which the spinner lands?

Is the chance of the colours matching.

Step-by-step explanation:

The possibility of the spinner landing on an orange side is

and the possibility of the marble being orange is in this case you have to remember, in the fraction, you have 4 possibilities and 1 desirable outcome, when you have two dependant possibilities you have to multiply them:

And the result of that multipliction is which is the probability of the marble and the spiner colours matching.

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.

noncoplanar points are points that do not lie on the same line.
