Answer: The answer is C.
Step-by-step explanation:
Because in the theory of the outcome is a 50/50 chance landing heads or tails. So, the theorectical probability is 1/2. Now the experimental must be 11/20.
Answer:
Probability will be 0.5779
Step-by-step explanation:
Number of tablets n = 19
Probability of defect rems that is p = 0.03
Here number of trials is fixed and probability of success = 0.03
Here p = 0.03
So q = 1 - p = 1 -0.03 = 0.97
By using binomial distribution
Probability is given by ![^nC_rp^rq^{n-r}](https://tex.z-dn.net/?f=%5EnC_rp%5Erq%5E%7Bn-r%7D)
So P(0 or 1) = ![^{19}C_0{0.03}^0{0.97}^{19-0}+^{19}C_1{0.03}^1{0.97}^{19-1}=0.5606+0.0173=0.5779](https://tex.z-dn.net/?f=%5E%7B19%7DC_0%7B0.03%7D%5E0%7B0.97%7D%5E%7B19-0%7D%2B%5E%7B19%7DC_1%7B0.03%7D%5E1%7B0.97%7D%5E%7B19-1%7D%3D0.5606%2B0.0173%3D0.5779)
Answer:
Step-by-step explanation:
Answer: concentration = 15.58%
Step-by-step explanation:
Given: mass of sugar = 24 g = 24 ml [ ∵ 1 g = 1 ml]
Volume of solution = Quantity of water + quantity of solute
= 130 +24 ml
= 154 ml
Concentration = ![\dfrac{mass\ of\ solute}{Volume\ of\ solution}\times100](https://tex.z-dn.net/?f=%5Cdfrac%7Bmass%5C%20of%5C%20solute%7D%7BVolume%5C%20of%5C%20solution%7D%5Ctimes100)
![=\dfrac{24}{154}\times 100\\\\\approx15.58\%](https://tex.z-dn.net/?f=%3D%5Cdfrac%7B24%7D%7B154%7D%5Ctimes%20100%5C%5C%5C%5C%5Capprox15.58%5C%25)
Hence, the concentration =15.58%
Nothing changes if you don't add anything.
Example:
10+10=20
20+0=20
nothing changes.
