Answer:

40% probability

Step-by-step explanation:

First, you need to look at the sample space or number of outcomes:

<h2>B B B R R</h2>

The sample space, or number of outcomes, is 5

If you randomly select one marble and then select another marble after replacing it, you are taking out 2/5 of the marbles in the jar.

<h2>B  B  B R  R</h2>

1/5 2/5 3/5 4/5 5/5

2/5 can be converted into a percentage by turning it into a decimal:

<h2>2/5 = .4</h2>

.4 can be converted into a percentage

<h2>.4 = 40%</h2>

This leaves you with the probability being 40%

now to split these minutes equally, we will divide them by 7 days of week
daily usage = 190/7 = 27.14 minutes
since we can not talk for 0.14 minutes, therefore,to equally split the remaining minutes, you should speak 27 minutes per day with one extra minutes remaining to be used on the day you choose
