the odds in favor of frank mckinnis winning a hot dog eating contest are 2:9the odds in favor of frank mckinnis winning a hot do

Ivahew [28]

Answer:

Consider the complete question is,

'The odds in favor of frank McKinney winning a hot dog eating contest are 2:9,

Determine the probability that Frank will win the contest,

Determine the probability that Frank will not win the contest'

Solution :

We know that,

Odds in favor : the ratio of the number of ways that an outcome can occur compared to how many ways it cannot occur.

We have,

$\frac{\text{Number of ways of winning the contest}}{\text{Number of ways of not wining the contest}}=\frac{2}{9}$

So, total outcomes = 2 + 9 = 11,

$\text{Probability}=\frac{\text{Favourable outcomes}}{\text{Total outcomes}}$

Thus, the probability that Frank will win the contest = $\frac{2}{11}$

And,

The probability that Frank will win the contest = $\frac{9}{11}$

2) A salesperson earns commission on the sales that she makes each month.

mixer [17]

Part A
Commission total = Commission 1+ Commission 2
Where
Commision 1 = 5% of first 45000
Commission 2 = 7.5% of the amount left after $5000 is subtracted
thus
Commision 1 = $5000x.05
= $250

Commission 2= $3000 x.075
= $225
Commission total = $250+$225
= $475
The total commission she earned is $475ion

Part B.
Total sales = Sales with 5% commission+Sales with 7.5% commission
Sales with 5%commission= $5000
Commision At 7.5% = Total commision -Commission with 5%
= $1375-$250
Sales x.075= $1125
Sales with 7.5% commision = $15000
Total sales = $5000+$15000
Total sales = $20000
Total sales for commission of $1375 is $20000
