surely you know how much that is.
Answer:
1/24
Step-by-step explanation:
To start, we can calculate the probability of each individual event:
<u>Getting the person right:</u>
1/2
<u>Getting the weapon right:</u>
1/3
<u>Getting the room right:</u>
1/4
Here, you're trying to find the probability of the intersection of the three events. This means we must multiply the probabilities of the independent events together.
1/2*1/3*1/4=1/24
or
0.0417
Note that we multiply the probabilities together when the previous event doesn't affect the probability of the next event. In general, questions that ask for the probability of a happening and b happening mean you multiply the probability of a and b (events that satisfy your demands are decreasing because you need BOTH events to occur).
On the other hand, questions that ask for the probability of a or b happening, meaning the events that satisfy your demands will increase (2 options versus 1), so you'd add the probabilities of a and b happening.
Hope that makes sense, let me know if you have any questions!
Volume of a cylinder is given by πr^2h
Volume of the cylindrical water cooler is π x (12/2)^2 x 15 = 3.14 x 36 x 15 = 1,695.6 in^3
Volume of water in the cylindrical cooler is 1,695.6 / 2 = 847.8 in^2
Number of drinking cups that can be filled from the cooler is 847.8/20.14 = 42 cups.
