The probability that you will win a game is
p
=
0.21
.

If you play the game 139 times, what is the most likely number of wins?
(Round answer to one decimal place.)
μ
=

Let
X
represent the number of games (out of 139) that you win. Find the standard deviation for the probability distribution of
X
.
(Round answer to two decimal places.)
σ =

The range rule of thumb specifies that the minimum usual value for a random variable is μ-2σ and the maximum usual value is μ+2σ. You already found
μ
and
σ
for the random variable
X
.

Use the range rule of thumb to find the usual range of
X
values. Enter answer as an interval using square-brackets and only whole numbers.
