Then Bangladesh will have to bat for at least four sessions in total and set a big target. If Bangladesh can set a target of 300 runs for Sri Lanka after the 1st session of the last day, then maybe Bangladesh has a chance of winning or the match will be drawn.
There is no possibility of Bangladesh drawing, rather they will surely lose. However, I did not expect such a bad performance from Bangladesh. Where they drew with Sri Lanka in the first match with equal performance, but in the second Test they lost miserably to Sri Lanka. Bangladesh were all out for 247 runs in their first innings, but Sri Lanka were all out for 458 runs in their first innings, taking a big lead of 211 runs. Bangladesh performed even worse in the second innings where they lost their six wickets for 115 runs, meaning that if Bangladesh performed very well, they could have gone up to 150 runs. Even then, it goes without saying that Bangladesh will be defeated.
