    Answer:

    P [ K > 3.95] = 0.5633

    Step-by-step explanation:

    The interpretation of the given question goes thus;

    Suppose that K is a random variable

    P[-3.95 ≤ K ≤ 3.95] = 0.725  

    where; P [ + 3.95 < K ] = P [K < – 3.95]

    P[K< 3.95] – P [K > – 3.95] =0.725

    P [K < 3.95] – [ 1- P[K < 3.95]] = 0.725

    P[k < 3.95] – 1 + P [ K < 3.95] = 0.725

    3.95 P [ K < 3.95] -1 = 0.725

    3.95 P [ K < 3.95] = 1.725

    P [ K < 3.95] = 1.725/3.95

    P [ K < 3.95] = 0.4367

    P [ K > 3.95] = 1 – P[K< 3.95]

    P [ K > 3.95] = 1 – 0.4367

    P [ K > 3.95] = 0.5633
