Answer 1

1. The Probability of an event can never be below zero, the lowest chance of probability would be zero

So the answer will be option "C".

2.Number of ways to succeed : 1

Number of possible ways : 4

So the answer will be option "B".

5. Event B is dependent on Event A because since the ball drawn in Event A was not put back, that effect the result of event B.

6. p(x=2 good) = 2C2(0.88)^2*(0.12)^0 = 0.88^2 = 0.7744

so the answer option will be "C"

7. Answer option is "B"

8.Answer option is "A"

9.Answer option is "A"
