Answer:

brainliest

Step-by-step explanation:

There is a probability of 83% that you will pick either a red or blue marble. (10 out of 12 total)

Answer 2

Given:

2 pink marbles (p) + 6 red marbles (R) + 4 blue marbles (B) in a jar

To Find:

The probability that the marble you pick will be red (R) or blue (B)

Solution:

Probability =

Number of red and blue marbles ÷ Total number of marbles in the jar

We must first calculate the total number of marbles in the jar

Given,

2 pink marbles (p) + 6 red marbles (R) + 4 blue marbles (B) in a jar

The total number of marbles in the jar =

= 2 + 6 + 4

= 12

Now, find the number of red and blue marbles present in the jar

Number of red and blue marbles in the jar =

= 6 + 4

= 10

Probability ( red or blue marble) ⇒

P( R + B) =  $\frac{10}{12} = \frac{5}{6}$

The probability that the marble you pick will be red or blue is  $\frac{5}{6}$
