Answer: Hence, the probability that he will get at least one lemon is 0.70.
Step-by-step explanation:
Since we have given that
Number of cars = 30
Number of lemon cars = 10
Number of other than lemon cars = 30-10 = 20
According to question, he bought 3 cars,
we need to find the probability that you will get at least one lemon.
So, P(X≤1)=1-P(X=0)=1-P(no lemon)
Here, P(no lemon ) is given by
so, it becomes,
Hence, the probability that he will get at least one lemon is 0.70.

Step-by-step explanation:
Answer:
A and D.
Step-by-step explanation:
(sin(x-y))/(cosxcosy)
(sinxcosy - cosxsiny) / cosxcosy
= sinx / cosx - siny/cosy
= tanx - tany.
So A is an identity.
B. (sin(x+y))/(sinxsiny)
= sinx cosy + cosx siny / sinxsiny
= cosy/siny + cosx/sinx
= 1/tany + 1/tanx which is not identical with 1-tanxtany.
C. tan ( x - pi/4) = ( tan x - 1) / (1 + tanx) : - not identical to tanx - 1.
D. cos( x + (pi/6) = cosxcos(pi/6) - sinxsin(pi/6)
= 0.866cosx - 0.5sinx
- sin(x - (pi/3) = -(sinxcos(pi/3) - cosxsin(p/3))
= - (0.5sinx - 0.866cosx0
= 0.866cos x - 0.5sinx.
which are identical.
