Choose a number B at random from the interval [0, 1] with uniform density. Find the probability that

(a) 1/3 < B < 2/3
(b) |B − 1/2| ≤ 1/4
(c) B < 1/4 or 1 − B < 1/4
(d) 3B2 < B

Step 1

For the provided information, the uniform distribution is B~U(a, b).

Here a=0 and b=1. The probability density function for uniform distribution is

f(x)=1/b-a.

a.  The required probability for 1/3<B<2/3 can be obtained as:

Step 2

b. The required probability for |B-1/2|≤1/4 can be obtained as:

Step 3

c. The required probability for B < 1/4 or 1 &minus...
