A bag contains 6 red jelly beans, 4 green jelly beans, and 4 blue jelly beans.
worty [1.4K]
The simplified probability would be 12/91.

There are 4 green jelly beans out of a total of 14 jelly beans.  The probability for the first bean would be 4/14.

Once the first jelly bean is removed, the probability that the second jelly bean would be red is 6/13 (the denominator decreases by 1 because of the first jelly bean that did not get put back).

Together the probability is (4/14)(6/13) = 24/182, which then simplifies to 12/91.

Sarah pays a 20% deposit for a new TV and then an extra $96. What’s the total cost?
mixer [17]

A deposit (in this case) is a portion of the TV paid in advance - 20% of the total cost. That means that the 96$ makes up the remaining 80% of the total cost, which I'll represent as <em>x</em>. From here, we can set up an equation to find the total cost x, since we have a relation to form it on - <em>the fact that 80% of x is equal to 96$.</em>

0.8x = 96

\frac{0.8x}{0.8} = \frac{96}{0.8}

x = 120  

The total cost of the TV is 120 dollars.
