Answer:
1/14
Step-by-step explanation:
Assuming you mean that there are 2 red, 2 green, and 4 blue marbles, there are a total of 8 marbles.
On the first draw, the probability the marble is red is 2/8.
On the second draw, there's one less marble, so the probability of selecting a green marble is 2/7.
The total probability is:
2/8 × 2/7 = 1/14

PART A
write two different, equivalent expressions for how much the rosebush will cost if the coupon is applied first and the 10% discount second. <em><u>d-(d-5)</u></em><em><u>.</u></em><em><u>10</u></em><em> </em>= 27.5 <em>(if you put d in as 30!)</em>
PART B
write an expression for how much the rosebush will cost if the 10% discount is applied first and the coupon is applied second. <em><u>d-(d*.10)-5</u></em><em> </em><em> </em>=22 <em>(if you put d in as 30!)</em>
PART C
which order will save marina more money? explain your reasoning.
<u>d-(d*.10)-5</u><u> </u>This equals less! if you put in 30 as an example
So, A) <u>d-(d-5).10 </u>B)<u> </u><u>d-(d*.10)-5</u><u> </u>C) <u>d-(d*.10)-5</u>
