EXACT ESTIMATIONS FOR SOME LINEAR FUNCTIONALS OF UNIMODAL DISTRIBUTION 
FUNCTIONS UNDER INCOMPLETE INFORMATION
Abstract. Exact estimations are found for the probability that a non-negative unimodal random 
variable μ gets in the interval (m – σμ,
 m + σμ) where the mode m coincides 
with fixed first moment 
and σμ2 
is fixed variance of random variable μ. 
Also, a brief important auxiliary information is given with examples, statements, and author’s notations, which simplify obtaining the main result. 
The results of this study may be useful in evaluating the probability of hitting the projectile zone when aimed shooting.
Keywords: linear functionals of unimodal distribution functions and their extremal values, transformation of Johnson–Rogers, exact generalized Chebyshoff inequalities for unimodal distribution functions
.
