Answer: 0.27
The events are independent, so we can multiply the probabilities.
P(A n B) = P(A) * P(B)
P(A n B) = 0.3 * 0.9
P(A n B) = 0.27
note: The 'n' represents the "intersection symbol", aka "horseshoe" or "upside down U".
The intersection of two events is like asking when the two events will occur simultaneously. Example: If A represents the event "it rains" and B represents the event "a person won a contest" then P(A n B) represents the probability of it raining and the person winning the contest.
Answer:
The area of the sector is 17/2 π
Step-by-step explanation:
pi = π
To solve this problem we first have to find the fraction that corresponds to this angle of the total, for this we must divide the angle that they give us by 2π radians, since that is the angle of a circle
(17π/9 rad) / (2π rad) = 17/18
Now we multiply the area of the circle by this fraction and we will obtain the area of the sector that we want
9π * 17/18 = 17/2 π
The area of the sector is 17/2 π
