A coin is tossed 200 times, if the probability of getting a head is 5/8, how many times tail is obtained in all in tossing the coin? ​

You would get tails 75 times, or 75:200

Step-by-step explanation:

5:8 = x:200

multiply 8 by 25 to get 200

multiply 5 by 25 to get x (125)

Probability to get heads is 125 so subtract 200 by 125

200 - 125 = 75

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.
