Step-by-step explanation:
melanin content Total
high low
moisture high 13 10 23
content low 47 30 77
Total 60 40 <u> </u><u>100</u>
Let A denote the event that a sample has low melanin content, and let B denote the event that a sample has high moisture content.
a) Total skin samples has low melanin content = 10+30=40
P(A)=
b) Total skin samples has high moisture content = 13+10=23
P(B) =
c) A ∩ B = Total skin samples has both low melanin content and high moisture content =10
P(A ∩ B) =
Using conditional probability formula ,

Answer:
54 mph
Step-by-step explanation:
Let s represent the slower speed. The product of speed and time is distance, which did not change between the two trips. So, we have ...
1.8(s +6) = 2(s)
10.8 = 0.2s . . . . eliminate parentheses, subtract 1.8s
54 = s . . . . . . . . divide by 0.2
