Enter an exact number as an integer, fraction, or decimal. P(19 < x < 35)

Question

Births are approximately uniformly distributed between the 52 weeks of the year. They can be said to follow a uniform distribution from one to 53 (spread of 52 weeks).

Answer 1

Probability = (d - c)/(b - a)

where d = upper limit of range of interest

c = lower limit of range of interest

b = maximum value

a = minimum value

for this problem d = 35, c = 19, b = 53 and a = 1

so probability = (35 - 19)/(53 - 1) = 16/52 = 4/13
