Step-by-step explanation:
pet supplier has a stock of parakeets of which 20% are blue parakeets
20/100 = 0.2 blue parakeets (success)
1-0.2 = 0.8 not parakeets (not success)
A pet store orders 3 parakeets from this supplier
we need to find the chance of getting exactly one blue from 3 parakeets
n=3, r=1, p = 0.2 , q=0.8
0.384
