Number defective=4
number of non-defective=total-defective
=20-4
=16
the questions asked for 1 defective
so we choose only 1 defective from 4 defective items
4C1

and for 1 non-defective
we choose only 1 non-defective from 16 non-defective items
16C1

we choose 2 items from 20 items
so 20C2

answer:
probability= [(4C1) * (16C1)] /(20C2)
=32/95

F(m)=m^4-6m^3+5m^2+10m-4 at m=4

Alexandra [31]

Answer:

F(m) = -12

Step-by-step explanation:

Given the function:

$F(m)=m^{4}-6m^{3}+5m^{2}+10m-4$

When m = 4, we substitute the variable 'm' for the number 4:

$F(m)=4^{4}-6(4)^{3}+5(4)^{2}+10(4)-4$

F(m) = 256 - 384 + 80 + 40 - 4

F(m) = -12
