How do I simplify this ?

b^3

Step-by-step explanation:

so basically if you spread this out it is

b*b*b*b*b

b*b

Since b/b is 1 you can cancel out the denominator and 2 b's in the numerator

that leaves you with b*b*b which is b^3.

Hope it helps!!

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%

1 1/5
