Question 1140366
<br>
There are 7 coins; the probability of choosing any one particular coin on each draw is 1/7.  The probability of specific outcomes on two successive draws is (1/7)*(1/7) = 1/49.<br>
Count the number of outcomes with a total of 30 cents or more using an organized list.<br>
Two things I can think of that you want to consider when making your list:
(1) at least one of the coins drawn must be the quarter
(2) quarter then dime (for example) is a different outcome than dime then quarter<br>
Then if you count 10 cases where the total is 30 cents or more (for example; not the right answer!), the answer to the question would be 10/49.
