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.
To find the x-intercept, substitute in 0 for y and solve for x.
Answer:
a) cosθ =
Step-by-step explanation:
<u><em> Step(i):</em></u>-
Given point ( x , y ) = ( - 2 , 3 )
We know that the polar co-ordinates
x = r cos θ and y = r sinθ
where
<u><em>Step(ii)</em></u>:-
x = r cos θ
cosθ
cosθ =
cosθ =
