A box has 3 one-dollar bills, 2 five-dollar bills, 2 ten-dollar bills, and 1 twenty-dollar bill. A student selects one bill from
the box at random. PART A Develop a probability model to compare the probability of selecting $5 to the probability of selecting $10. Explain. PART B how does the probability of selecting $1 compare to the probability of selecting $20? explain
Part A: The probability of selecting 5 is 2/8 and the probability of selecting 10 is also 2/8 and both of them are the same, 1/4.
Part B: The probability of selecting a one dollar bill is 3/8 and the probability of selecting a twenty dollar bill is 1/8 because there are 3 one dollar bills in 8 bills and 1 twenty one dollar bill in 8 bills only.
Given that the hypotenuse of the isosceles right triangle = 14 , ⇒ the length of each leg = 14 √ 2 = 7 √ 2 Check : ( 7 √ 2 ) 2 + ( 7 √ 2 ) 2 = 196 = 14 2 (OK)
A unit of volume equal to that of a cube having sides each one decimetre in length, equal to 10-3 cubic metres and 1 litre. Commonly used in fluid measure and for engine sizes.
