Adam goes to the grocery store to buy cereal. the shelves contain 9 boxes of brand a and 6 boxes of brand b. he selects one brand at random and then put it back. another person does the same thing. what is the probability they both selected brand a?

We can first find the probability of the first person picking Brand A, which would be:

9/6+9

=9/15

=3/5

We can then find the probability of the second person choosing brand A:

(9-1)/(6+9-1)

=8/14

To find the probability they both select Brand A, we could multiply them together:

3/5 x 8/14

=12/35

Therefore the answer would be 12/35.

Hope it helps!

Answer is 50.

Step-by-step explanation:

Solving:

√64= √2x2x2x2x2x2 =√2^2 x2^2 x2^2 =2x2x2=8

√16 = √2x2x2x2 = √2^2x2^2 = 2x2 = 4

√-1 = i

Putting values:
