Acoin is biased to display heads 75% of the time. it is tossed 20 times, and the outcome is recorded. the most improbable simulation for this coin is heads.

option D is correct, i.e. 15 heads

Step-by-step explanation:

If the coin is biased to display heads 75% of the time, and it is tossed 20 times, then it is quite possible that it will show heads 75% of the time of 20 tosses. It means the most improbable simulation for this coin is (75% of 20) heads.

So, the most improbable simulation for this coin is = 0.75 x 20 = 15 heads.

Hence the answer is option D, i.e. 15 heads.

The answer is 9.

Step-by-step explanation:

4 and 5)16.97 or 12√2

6)15.59 or 9√3

7)y = 15.59 or 9√3     x =27

8)17.80
