Dochulacht
| Tearma | Míniú | Sampla |
|---|---|---|
| Dódhéanta (impossible) | Is e an dochulacht go dtarloidh rud eigin na 0/ the probabilility of something happening is 0 | |
| Cinnte (Certain) | Is e an dochulacht go dtarloidh rud eigin na 1/ the probabilility of something happening is 1 | |
| Seans cothrom/ Seans 50-50 (Even chance/ 50-50 chance) | Msh. Bionn se chomh dóchúil céanna go bhfaighfí an aghaidh nó cúl nuair a chaitear bonn san aer/ There is an equal probability of getting heads or tails when a coin is thrown in the air. | |
| An Scala Dochulachta (the probability scale) | Taispeannan se duinn cen dochulacht ata ann go dtarloidh rud eigin. Teann se o 0 go dti 1./ it shows us how likely an event is to happen. It goes from 0 to 1. | |
| Bunphrionsabal an chomhairimh (fundamental principle of counting) | Ma bhionn m fothoradh feideartha ar rud amhain agus n fothoradh feideartha ar rud eile, bhionn m x n fothoradh ar an da rud. If one event has m possible outcomes and another event has n possible outcomes then the two events have m x n possible outcomes. | |
| seansúlacht (chance) | Ni bhionn a fhios ag duine ar bith cen fothoradh a bheadh ann trath ar bith/ nobody knows what the outcome will be | |
| Fothoradh (outcome) | Toradh ata feideartha nuair a deanann tu trial/ a possible result when you carry out an experiment | |
| Chomh dóchúil lena chéile (equally likely) | Seans ceanna ag gach ceann de na fothorthai/ each result has the same chance of appearing | |
| Neamhdhóchúil (unlikely) | dochulacht 25% / probabilility of 25% | |
| Randamach/ Random | Níl tú abalta an toradh a thuar/ You are unable to predict the outcome | |
| Laofa / Biased | Nuair atá fothoradh amhain níos dóchúil/ When a certain outcome is more likely | |
| Fothoradh fabhrach/ Favourable outcome | Is é seo ná an fothoradh atá ag teastáil uait/ This is the outcome that you want | |
| Spás Samplach/ Sample space | An liosta na bhfothorthaí féideartha go léir/ The list of all possible outcomes | |
| Minicíocht ionchais/ Expected frequency | Dóchúlacht x líon na dtrialacha/ probabililty x number of trials | |
| Léaráidí Crainn/ Tree diagrams | Is féidir na fothorthaí féideartha ar dhá theagmhas nó níos mó a thaispeáint lé iad seo/ The possible outcomes of two or more events can be shown using these | |
| Dochulacht (probability) | An seans go dtarloidh rud eigin. Caithfaidh sé a bheith idir 0 agus 1/ The chance that something will happen. It must be between 0 and 1. |
