Jan's house has four leaking taps. An average of 34 cL of water leaks from each tap every day. How many litres of water is lost
pshichka [43]

Answer: 42.16l

Step-by-step explanation:

First, we should note that August has 31 days. Since Jan's house has four leaking taps and an average of 34 cL of water leaks from each tap every day. The four taps will leak (34 × 4) = 136 cL everyday.

The amount of litres of water that is lost from these four taps in August would be:

= 136cL × 31

= 4216 cL

= 42.16L

We should note that 100cL = 1L

What if we draw three socks from the box instead. what is the probability that we draw a matching pair? (having all three socks
frutty [35]

There is a chance of 1/16*1/15 that she gets the specific socks pair according to laws of probability and the counting principle but thats not how it will work over here.

As we should be guaranteed that she gets the number of socks she obviously must take out around 9 socks as we are taking the worst case scenario where all the socks that come out are the different ones so the ninth sock must match any of the others.

But if we draw three socks obviously the probability is 1/16*1/15*13/14 as we dont want the third one to be same. We can multiply the answer by 3 as it can be in three different orders.
