Among persons donating blood to a clinic, 85% have $\displaystyle \text{Rh}^+$ blood (that is, the Rhesus factor is present in their blood). Six people donate blood at the clinic on a particular day.

Find the probability that at least one of the five does not have the Rh factor (confused on how this is worded).

Plus, there are 6 people donating per day not 5.
