Answer:
The probability that a club member picked randomly is female, given that the person prefers swimming on weekends, is 0.8 = 80%.
Step-by-step explanation:
We use the conditional probability formula to solve this question. It is
In which
P(B|A) is the probability of event B happening, given that A happened.
is the probability of both A and B happening.
P(A) is the probability of A happening.
In this question:
Event A: Prefers swimming on weekends.
Event B: Being female.
25% prefer swimming on weekends
This means that
It is found that 20% of the members in that city prefer swimming on weekends and are female
This means that
So
The probability that a club member picked randomly is female, given that the person prefers swimming on weekends, is 0.8 = 80%.

Answer:
16 Nickles and 14 Dimes
Step-by-step explanation:
What we know
- n + d = 30
- .05n + .1d = 2.2 (total change equals $2.20)
- (.05n + 0.1d = 2.2) -10
- -.5n - d = -22
- .5n = 8
- n = 16
(2a*5)-3 is the answer best way to say it can't explain
