Answer:
mcmmmmmjhfj j y types and I love t
(a) P( fifth one is bad) = P( first 4 are OK) * P(5th is bad)
= (0.98)^4 * 0.02 = 0.0184 or 1.84%
(b) this will be (0.98)^10 = 81.70%
So for this one, all you have to do is plot the points it's giving you :)
Then you connect the lines and you get a shape from A-b-c-d
The answer is 3
because 18/27 = 2/3
F(a)= -3a+2b
Hope this helps!
