Answer:

The probability that the next color will be red is: \dfrac{2}{3}

Step-by-step explanation:

The probability of an event is defined as:

Probability=(Total number of favourable outcomes)/(Total number of outcomes )

Here we have to find the probability that the next colour is red is given by:

<em>The recordings are given as:</em>

B  R  Y  R  R  R  R  Y  R  B  R  R

Number of outcomes that red will come up=8

Total number of outcomes=12

Hence the probability is given by:

Probability=\dfrac{8}{12}=\dfrac{2}{3}

Answer:

B

Step-by-step explanation:

If you're looking for direct correlation, you're looking for a proportion for the second box. So you set the ratio of 2.5:5.5 up as a fraction. 2.5/5.5 and set it equal to the second box 3/x.

2.5     =      3

5.5             x

cross multiply

16.5=2.5x

and divide

16.5/2.5 and you get your answer
