Let number of throws he take = 100.
So, he will get success 80 times.
for these 80 success he will get 80 chances more to throw according to one-and one, so 80% of these 80 will be 64.
so total points he will score in 100 one-and one = 80+64 = 144.

so the avg. =144/100.

so answer = 1.44.

Succeeds both time: 2* 0.8*0.8 = 1.28
0.16+1.28 = 1.44
