0.5

0.25

0.7

0.24

0.29

0.65

Answer 1

Binomial Experiment :

The probability of success , denoted by p, is exactly the same from one trial to another. The trials are independent; that is, the outcome on one trial does not affect the outcome on other trials.

Given,

probability of success on trial 5 is 0.7.

As The probability of success , 0.7, is exactly the same from one trial to another.

probability of success = 0.7 for any trail

The trials are independent; that is, the outcome on one trial does not affect the outcome on other trials.

Therefore,

probability of success on trial 9 = Probability of success =0.7

probability of success on trial 9 = 0.7

Answer : 0.7
