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

P(largest or smallest) = 0.30 + 0.20 - 0.15

Step-by-step explanation

You combine the chances of doing the largest and smallest, without the chance of riding both.

P(largest or smallest) = 0.30 + 0.20 - 0.15

Step-by-step explanation:

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2
