An amusement park reports that the probability of a visitor riding its largest roller coaster is 30 percent, the probability of
a visitor riding its smallest roller coaster is 20 percent, and the probability of a visitor riding both roller coasters is 15 percent.
Which equation can be used to calculate the probability of a visitor riding the largest or the smallest roller coaster?
P(largest or smallest) = 0.30 - 0.20
P(largest or smallest) = 0.30 + 0.15-0.20
P(largest or smallest) = 0.30 +0.20 -0.15
P(largest or smallest) = 0.30 + 0.20
You want to get the total amount Henri has which is $14 then subtract the flat fee. 14-1.25=12.75, He has $12.75 left to pay for miles, Since the taxi charges .75 a mile, you get $12.75/.75= 17 Henri has enough to pay to ride 17 miles.
