java - Random but most likely 1 float -

i want randomize float

there 95% chance 1
there 0.01% chance < 0.1 or > 1.9
it never becomes 0 or 2

is possible using random.nextfloat() several times example?

a visual illustration of probability:

you need find function f such that:

f continuous , increasing on [0, 1]
f(0) > 0 , f(1) < 2
f(0.01) >= 0.1 , f(0.99) <= 1.9
f(x) "about 1" 0.025 <= x <= 0.975

and take f(random.nextdouble())

for example, math.tan(3*(x-0.5))/14.11 fits this, expression i'd use:

math.tan(3*(random.nextdouble()-0.5))/14.11

the probability distributed as:
