Step-by-step explanation:
This problem is
boys + girls = total
Boys = 442
Girls = 15% of the total
Therefore, substituting in, gives us:
442 + .15t = t, where t is total
Then 442 = .85t and
t = 520
Answer:
0.384
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
To do this multiply 1840 by 182. This gives you 334,880.
