What is the probability of getting 2 tails if a coin is tossed 4 times?
1/2*1/2*1/2*1/2+1/2*1/2*1/2*1/2+1/2*1/2*1/2*1/2+1/2*1/2*1/2*1/2+1/2*1/2*1/2*1/2+1/2*1/2*1/2*1/2+1/2*1/2*1/2*1/2+1/2*1/2*1/2*1/2= 1/2
What is probability of tossing 10 more tails in a row?
With an honest coin, the probability of tossing 10 consecutive tails is(1/2)10 = (1/1024) = 0.0009766 = 0.09766 percent(rounded)regardless of what may have happened before.
What is the variance of these four scores 0 1 1 2?
Variance = sigma((value - mean)2) / (# values - 1) Mean = (0+1+1+2)/4 = 1 Variance = ((0-1)2+(1-1)2+(1-1)2+(2-1)2)/(4-1) Variance = (1+0+0+1)/3 Variance = 2/3 Variance ~ 0.667
What is the probability of heads heads tails tails heads heads on six flips of a coin?
(1/2)*(1/2)*(1/2)*(1/2)*(1/2)*(1/2) = 1/26 = 1/64
A fair coin is tossed four times. What is the probability of getting some combination of three heads and one tail regardless of the order?
The probability of getting a combination of three heads and one tail regardless of theorder when you toss a coin four times is:P(THHH or HTHH or HHTH or HHHT) = P(THHH) + P(HTHH) + P(HHTH) + P(HHHT) =1/2(1/2)(1/2)(1/2) + 1/2(1/2)(1/2)(1/2) +1/2(1/2)(1/2)(1/2) + 1/2(1/2)(1/2)(1/2) = 4/16 = 1/4
Is a solution with a pH of 2 twice or half as acidic as a pH of 1?
No. As the pH scale is logarithmic, a solution with a pH of 1 is 10 times more acidic than a solution with a pH of 2.
If stomach juice of pH 1 is 10 time more acidic than lemon juice of pH 2 and 100 times more acidic than vinegar of pH 3 how much more acidic is it compared to a solution of pH 6 If n is the pH value o?
The ratio is 1:1 000 000.
What is more acidic a pH of 2 or 3?
pH 2. The lower the number is the more acidic it is. pH 7 is neutral, pH 14 is least acidic. 5.4 is considered acid rain.
How many times more acidic is a solution of pH 1 than a solution having pH 2?
To first answer this question you must know how the PH scale works. Essentially the PH scale is a logarithmic scale. A logarithmic scale unlike a linear scale (you know the scales that go from 1, 2, 3, etc.) works using exponential increments. For the PH scale every time you go one number down the solution the item in question becomes ten times more acidic than the number above. Therefore to ultimately answer your question a solution with a PH of 1 is ten times more acidic than a solution that has a PH of 2.
What pH values indicates a solution with the highest concentration of hydrogen ions pH equals 1 or pH equals 2 or Ph equals 7or pH equals 14?
pH = 14 is basic pH = 7 is neutral pH - 1 and 2 are acidic; pH = 1 is more acidic than pH = 2 Therefore a solution at pH 1 has higher concentration of H+ than at pH 14
Which is more acid the pH of 6 or the pH of 2?
A pH of 2 is much more acidic than a pH of 6
How does a solution with a pH of 2 compare to a solution with a pH of 7?
A pH 2 solution is 100,000 times more acidic than a pH 7 solution. pH 2 is acidic whereas pH 7 is neutral
How much more acidic is a solution of pH 2 than of pH 5?
. Since the pH scale is determined by log it is 10 to the power of 3 more acidic so it's 1000 times more acidic
What is more acidic lemon pH equals 2 soap pH equals 10 tomato pH equals 4 or ammonia pH equals 11.5?
The answer is lemon is the most acidic with pH 2; the next most acidic is tomato with pH 4.The soap with pH 10 is alkaline; and ammonia with pH11.5 is more alkaline than the soap.To understand pH, always remember that the values from 1 to 7 are all acidic, neutral is 7.5, and all the values from 8 to 14 are alkaline.
What is the pH in the stomach?
Between 1 and 2. Increases to about 6 or more after you have eaten something, as it is normally not that acidic.
How much stronger is pH 2 compared to pH 6?
A pH of 2 is 10,000 times more acidic than a pH of 6.
What is the most acidic pH 10 pH 3 pH 2 pH 6 pH 8 pH 12 pH 1 pH 7.5?
The lower the pH, the more acidic the solution is. Remember, pH 7.0 is H2O. As pH decreases below 7, the solution's acidity increases. As pH increase above 7, the basicity of the solution increases. Hence, in the choices you provided, pH 1.0 is most acidic.
