Lola pulls two marbles from a bag containing four red marbles, four blue marbles, and 12 yellow marbles without replacing them. what is the probability that she pulled out a red marble first and a yellow marble second? express your answer in decimal form, rounded to the nearest hundredth.

The probability of that she pulled out a red marble first and a yellow marble second is:

0.13

Step-by-step explanation:

It is given that:

Lola pulls two marbles from a bag containing four red marbles, four blue marbles, and 12 yellow marbles without replacing them.

This means that there are a total of:4+4+12=20 marbles.

Now we are asked to find the probability that she pulled out a red marble first and a yellow marble second.

The probability of choosing a red marble out of 20 marbles is:

and the probability of choosing a yellow marble on the second draw(i.e. now we have to choose among the 19 remaining marbles) is:

Number of yellow marbles in the bag/19

=

Hence, the probability of choosing a red and then a yellow marble is:

.

Hence, to the nearest hundredth the probability is:0.13

the answer is c: divide the arc's degree measure by 360°, then multiply by the circumference of the circle.

a is 8.b is 10.c is 10.5. d is -.5

step-by-step explanation:

just minus the smallest number from the biggest.
