a) the Probability p( red, red, red) is 0.83%.
b) the probability p(white, red, white) is 0.
<u>Step-by-step explanation:</u>
The total number of marbles = 3+6+1.
=10.
a) to find the Probability p( red, red, red).
p( red, red, red)=
p( red, red, red)=×
×
.
p(red,red,red)= 0.0083.
p(red,red,red)=0.83%
b)to find the probability p(white, red, white).
p(white, red, white) is 0.
Since there is only one white.
Answer:
2.25 (or ) g/mL
<u>Skills needed: Density</u>
Step-by-step explanation:
1) Briefly, let's cover what density is:
- It is
- Measures the mass per unit of volume
- In this situation the formula for density is:
---> is the final mass
---> is the initial mass
---> is the final volume
---> is the initial volume
2) In this case, we start out with a mass of 180 grams as stated in the problem, and also 50 mL of water initially.
This means that:
- is 180 g
- is 50 mL
3) Also, we end up with 270 g in mass, and 90 mL of water finally.
- is 270g
- is 90 mL
4) We can find density by substitute given the values above:
5) Our answer is 2.25 g/mL (since mass is grams (g), and volume is milliliters (mL) in the problem above).
