Chapter 6.2, Problem 15E
Solution

To find: the probability of getting 12 heads in 20 tosses of a coin.

The probability of getting 12 heads in 20 tosses of a coin is 0.1201.

Given:

A coin is tossed 20 times.

Concept used:

For a binomial experiment, the probability of k successes in n trails is,

  Pksuccesses=Cnkpk1pnk , where p is the probability of success.

  Cnr=n!r!nr!

Calculation:

The probability of getting a head in tossing a coin is p=0.5 .

Because the coin is tossed 20 times, n=20 .

Now the probability of getting 12 heads is,

  Pk=12=C20120.51210.52012=20!12!2012!×0.5120.58=20×19×18×17×16×15×14×13×12!12!×8×7×6×5×4×3×2×1×0.520=0.1201
