Total number of balls = 100

Number of balls with odd numbers = 50
Number of balls with number greater than 80 = 20
Number of balls greater than 80 and is odd = 10
⇒ Number of favourable outcomes = 50 + 20 - 10 = 60

P(odd or greater than 80) = 60/100 = 3/5

Answer: 3/5

A motorcycle can travel 60 miles per gallon. Approximately how many gallons of fuel will the motorcycle need to travel 40 km?
Semenov [28]
The first thing to note is since one gallon= 60 miles then 1/2 gallon= 30 miles, now I know 1/2 is not an answer but it is easiest to decrease in moderate amounts. 1/2 gallon= 48 Km so we are close, and 1/2=0.5 so if we brought it down to 0.42 we would have 25.2 miles and 25.2 miles = 40.32. The question wants to know the approximate number and 40.32 is the closest we are going to get so the answer is 0.42
