Step-by-step explanation:
Calculate EF using the distance formula
d =
with (x₁, y₁ ) = E(1, 3) and (x₂, y₂ ) = F(- 2, 8)
EF =
=
=
= ≈ 5.83 ( to 2 dec. places )
The probability to choose letter n is 
. After drawing letter n there left 25 letters and the probability to choose the letter w is 
. After drawing two letters n and w there left 24 letters and then the probability to choose letter b is 
. After drawing three letters n, w and b there left 23 letters, so the probability to choose letter t is 
.
Using the product rule for probabilities, you can obtain that
