If you flip three fair coins, what is the probability that the first to flips will both be heads, and the third flip will be either heads or tails

Which ahows the graph of the solution set of 6x+4y< 12

Use the frequency distribution, which shows the number of american voters (in millions) according to age, to find the probability that a voter chosen at random is in the 18 to 20 years old age range. ages frequency 18 to 20 5.9 21 to 24 7.7 25 to 34 20.4 35 to 44 25.1 45 to 64 54.4 65 and over 27.7 the probability that a voter chosen at random is in the 18 to 20 years old age range is nothing. (round to three decimal places as needed.)

Use circumcenter theorem to solve for the given values
