13. probability of getting three 1's 2/5*2/5*2/5= 8/125=6.4% 14.getting one five=1/5 (same as 13 solution) 6.4% 15.less than 3=3/5 turn 3 times 3/5*3/5*3/5=27/125=21.6% 16.no two=4/5. 4/5*4/5*4/5=64/125=51.2% 17. odd=4/5 ( same as 16 solution) 51.2% 18. getting 1,2,3=4/5. (same as above) 51.2%
comment if you want me to explain any of them in detail
