A student takes an exam containing 18 true or false questions, if the students guesses, what is the probability that he will get less than 10 but more than 7 questions right

b.) 160 miles on a 5 gallons car

step-by-step explanation:

240/10=24 miles/gallon

160/5=32 miles/gallon

30/1=30 miles/gallon

168/6= 28 miles/gallon

32 miles/gallon is the most amount, so this is the best.
