The only way to know for certain if you will receive a visa or not is to apply for one and see if you are accepted or rejected.
In your specific case, with a rejection for deception from a country that shares information with the country you intend to travel to, your odds of success are probably not good.
Note, however, that a way to make your odds even worse would be to attempt to conceal your Irish refusal from the UK authorities; they will quite likely be able to find out anyway, and then you will be seen as attempting to deceive the UK as well, which is not a good position to be in.
