Let d represents the event that a radar detects an aircraft.
So:
Required: Determine the probability that a radar detects three before it fails to detect 1.
This event is represented as: d d d d'
And the probability is calculated as thus:
Using complement rule:
So, we have:
2³ + 3² = 2*2*2+3*3= 8+9=17
a=2,
b=3,
P= 17,
2,3,17 are all prime numbers
