Answer:
0.119
Explanation:
50 independent fair games
Mean will be 50/2 = 25
Standard deviation of the loosing probability is :
* 10 = 33.536
we have to loose 33 times out of 50 games.
To find the approximate probability we use z- value table.
z value =
z - value = 2.2659
Looking at the z-value table we get 0.119.
