Answer:
P(black) = 2/3
Step-by-step explanation:
We need to find the total number of marbles
2 red marbles+ 3 white marbles+ 10 black marbles = 15 marbles
To find the probability that Sam chose a black marble, we take the number of black marbles and divide by the total number of marbles
P(black) = black marbles/total marbles
= 10/15
Divide the top and bottom by 5
= 2/3
X = 6
9/12 = 0.75
6/8 = 0.75
The missing number is 6. 3.6-.65 = 2.95
3.6 - 2.95 = .65

So we are given that he ordered a $15 meal
now we need to find how much will he have to pay with tax and tip
so first we find the sales tax of the meal
5% * 15 = 3/4 or 0.75
and the tip
15% * 15 = 9/4 or 2.25
we will add that to the meal price to find the total
15 + 2.25 + 0.75
total is 18
So <span>If Allam ordered a $15 meal, we will have to pay $18 with tax and tip

Hope this helps :)
