Answer:
The answers to the questions are;
(a) P(At least 1 defective)
= 0.9883.
(b) P(At least 1 defective)
= 0.6409.
Step-by-step explanation:
There are 110 cards and 20 defectives.
a) The probability of at least one defective is given by
P(At least 1 defective) = 1 - P(0 defective)
P(0 defective) = 20C0 × (90C0)/(110C20) = 0.0116
1 - 0.0116 = 0.9883
b) For a set of 110 boards that has 5 defective and 105 non-defective
P(At least 1 defective) = 1 - P(0 defective)
P(0 defective) = (20C0)(90C5)/(110C5) = 0.35909
1-0.35909
= 0.6409
equation of line in slope intercept form is
y = mx + c
where m is slope.
putting point (0,5) in equation
5 = m × 0 + c
c = 5
now equation is
y = mx +c
y = (-1/2)x + 5
answer is option D
20% greater = 1.2 times
so 10.2 x 1.2 is the answer. it is C.
