marble. If Marcia pulls 10 red marbles, how many blue marbles does she pull?

Answers

Answer:

She pulls 5 blue marbles

Step-by-step explanation:

Let x be the number of blue marbles

We are given that In her experiment, she finds that she is twice as likely to pull a red marble as a blue marble.

So, Number of red marbles = 2x

We are given that Marcia pulls 10 red marbles

So, $2x = 10$

$x =(10)/(2)$

x=5

Hence She pulls 5 blue marbles
