PLEASE HELP

A bag hes 10 red marbles, 3 green marbles,
7 yelow marbles, and 5 blue merbles. What is
the probability of crowing a red marble and
then g, blue, marble without replacing the first?

Answer 1

`(3)/(5)`

Explanation:

Probability is the chance of an event happening. One finds the probability of an event by using the following general formula,

`(desired)/(total)`

In this case, the desired outcome is pulling whether a red or blue marble from the bag, the desired equals the sum of the number of red and blue marbles.

(red) + (blue)

= 10 + 5

= 15

The total number of marbles is the sum of all the number of marbles in the bag.

(red) + green) + (yellow) + (blue)

= 10 + 3 + 7 + 5

= 25

Now substitute these values into the formula to find the probability, then simplify,

`(15)/(25)`

Divide both the numerator and denominator by (5),

`(3)/(5)`
