Len is planning a three hour trip down the Allenem River and back to his starting point. He knows that he can paddle in still water at 3 mi /h and that the rate of the current is 2 mi /h. How much time can he spend going downstream? How far downstream can he travel

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%

i think the answer is b.

step-by-step explanation:

not 100% sure though.
