    0.0268.

    Step-by-step explanation:

    This question can be solved using the binomial theorem.

    Total attempts = n = 11

    Required attempts = r = 5

    Probability of success = p = 3/4 = 0.75

    Binomial Theorem formula:

    P (X=r) = nCr * p^r * (1-p) ^ (n-r).

    Substituting the values:

    P (X=5) = 11C5 * 0.75^5 * 0.25^6 = 0.0268 (to the nearest 3 significant figures).

    So the probability that exactly 5 free throws are made out of 11 is 0.0268!
