Answer:
Ans =C(4,1),(-4,1),(4,6),(-4,6)
There are 45C4 = 148,995 ways to choose 4 calculators out of a group of 45.
There are 33C4 = 40,920 ways to choose 4 calculators that are not defective.
The probability that at least one is defective is (148,995 -40,920)/148,995 ≈ 0.725.
It should mean that the vehicles in the any vehicle lane are generally slower than the cars only lane.
Answer:
If g(t) = t^2 - 5t, then G = t - 5
If f(t) = 2t + 4, then F = 2( t + 2) / t (over t)
If (g * f)(5), then 5gf
