Answer:

  (d) 0.06

Step-by-step explanation:

A suitable calculator or app can tell you the value of the binomial distribution, as can many web sites.

__

formula

The value can be calculated "by hand" from ...

  B(n, p, x) = C(n, x)·p^x(1-p)^(n-x)

where C(n, k) = n!/(k!(n-k)!)

__

application

For your values, this is ...

  B(10, 0.75, 5) = 10!/(5!·5!)×(0.75^5)(0.25^5)

  = (10·9·8·7·6)/(5·4·3·2·1)(0.1875^5) ≈ 252(0.0002317) ≈ 0.0584

Rounded to 2 dp, that's 0.06.
