Question

A coin is tossed $75$ times and head comes $25$ times. Find the probability when a coin is tossed that a tail will come.

• A. $\frac{1}{2}$
• B. $\frac{1}{3}$
• C. $\frac{2}{3}$
• D. $\frac{1}{4}$

Answer 1

Answer: (C)

$\frac{2}{3}$

$n\left(S\right)=75$

$n\left(E\right)=No.oftimeswhentailhascome=75-25=50$

$P\left(A\right)=\frac{Numberoffavorableoutcomes}{TotalNumberofpossibleoutcomes}$

$P\left(A\right)=\frac{50}{75}=\frac{2}{3}.$
