Its because its perpendicular and also because if the angle which is 90 degrees and if it is corresponding to another angle that angle would also be 90 degrees and so if there's and angle missing just look for the corresponding one and that one will be the same degree.
Answer:
P(0≤T≤400)=0.3296
Step-by-step explanation:
we know probability density function is
probability that bulb will fail within first 400 hours
P(0≤T≤400)=
P(0≤T≤400)=
=
=
=1-0.67032 = 0.3296
so about 32.96 % bulb will fail within 400 hrs.
Answer:
Step-by-step explanation:
Given that among employed women, 35% have never been married. Select 11 employed women at random.
a) probability for success in each trial p = 0.35 and no of trials = n =11
b) the probability that exactly 3 of the 11 women in your sample have never been married=
P(X=3) =
c) the probability that 2 or fewer women have never been married
