Answer:

0.0083 = 0.83% probability that the boys will stand in alphabetical order from left to right in the picture

Step-by-step explanation:

Probability:

A probability is given by the number of desired outcomes divided by the number of total outcomes.

Arrangments of x elements:

The total number of arrangments of x elements is given by:

A_{x} = x!

Desired outcomes:

Standing in alphabetical order, so only 1 possible outcome, which means that D = 1

Total outcomes:

Arrangments of 5 people, so

T = A_{5} = 5! = 120

Probability:

p = \frac{D}{T} = \frac{1}{120} = 0.0083

0.0083 = 0.83% probability that the boys will stand in alphabetical order from left to right in the picture

D + q = 40
.10d +.25q= $7.75

d +q = 40
d =40-q
.10(40-q) +.25q= $7.75
4 - .10q + .25q =7.75
4 +.15q =7.75
4-4 +.15q =7.75-4
.15q= 3.75
.15q/.15 = 3.75/.15
q = 25

d =40-25
d = 15

Check
.10(15) +.25(25)= $7.75
1.5+6.25=7.75
7.75=7.75
