P (blue, blue) is 2/14, which simplifies to 1/7.
If only one marble was being picked, the probability would have obviously been 4/14. Since the first picked marble was placed back into the bag and the chances are the same for a second blue one, I think all you have to do is halve the probability to produce 2/14.
Answer: 134 cookies
Step-by-step explanation: First we want to find the total amount of cookies Brain bought. Simply multiply 14 x 9 to find the total amount of cookies bought.
14 x 9 = 126 cookies.
Since Brian already had 8 cookies in the jar, we will simply add the new amount of cookies he bought to the cookies in the jar left.
126 + 8 = 134 total cookies that Brain has now.
