A couple decides to keep having children until they have a girl, at which point they will stop having children. They also agree to having a maximum of three children. The table below shows the probability distribution of X=, equals the number of children such a couple would have. X=# of children 1 2 3
P(X), .5 .25 .25
Given that \mu_X=1.75μ
X
​
=1.75mu, start subscript, X, end subscript, equals, 1, point, 75 children, find the standard deviation of the children such a couple would have.
Round your answer to two decimal places.
\sigma_X\approxσ
X
​
≈sigma, start subscript, X, end subscript, approximately equals
children
