probabilities is pronounced prah-buh-BIL-uh-teez (/ˌpɹɑbəˈbɪləˌtiz/). Probabilities refers to numerical measures of how likely outcomes are in a given situation, usually expressed as a ratio or percentage. In statistics, it denotes the likelihood of events under uncertainty, often underpinning predictive models. The term is plural, encompassing multiple probability values or a distribution of likelihoods across outcomes.

- Commonly you might flatten the vowels in the unstressed syllables, turning /ə/ into a reduced or omitted sound, which blurs syllable boundaries. - You may also tilt stress toward the first or second syllable, saying pro-BA-bil-i-ties with incorrect emphasis; keep primary stress on the 3rd syllable (ˈbɪl). - Finally, the final -ities can blur into /ɪz/ or /iz/; practice ending sharply with /tiz/ to land the suffix clearly.
"Researchers compare the probabilities of several competing hypotheses."
"The probabilities of rain increase as the front approaches, affecting travel plans."
"She calculated the probabilities of different outcomes before running the experiment."
You say /ˌprɒb.əˈbɪl.ɪ.tiz/ in US/UK/AU. The primary stress is on the third syllable: pro-ba-BIL-i-ties. Start with /ˈprɒb/ (a rounded, short o), then /ə/ a quick schwa, then /ˈbɪl/ with a short i, another /ə/ schwa, and end with /tiz/ as /tiz/. Quick tip: ensure the suffix -bi-lities carries the main beat so the flow lands naturally in two clips: pro-BA-bil-i-ties.
Two common errors: (1) stressing on the wrong syllable, saying pro-BAB-il-i-ties or pro-BA-bil-i-ties; (2) mispronouncing the final -ties as /siːz/ or /tiːz/ instead of /tɪz/. Correction: keep the main stress on the 3rd syllable (ˈbɪl), and pronounce the ending as /-tiz/ with a short, clear /ɪ/ before /z/.
US/UK/AU share /ˌprɒb.əˈbɪl.ɪ.tiz/ or /ˌprəˈbæ.bɪl.ɪ.tiz/ in some faster speech, but rhoticity and vowel quality vary: US is rhotic and tends toward a stronger /ɹ/ and a clearer /ɒ/ in the first syllable; UK often reduces to /ˌprəˈbɪl.ɪ.tiz/ with a schwa in the first syllable; AU tends toward a centralized /ə/ in unstressed positions and a slightly more clipped ending. Overall, the main stress pattern remains on the third syllable, but vowel reductions differ.
Because it’s a multi-syllabic word with three closely spaced vowels and a multi-consonant cluster: pro-BA-bil-i-ties. The mid vowels /ɒ/ or /ə/ can be challenging in rapid speech, and the final /-bɪlɪtiz/ sequence requires precise tongue positioning to avoid slurring. Practice easing between syllables and maintaining the /t/ before the final /ɪz/ to prevent a run-together ending.
A distinctive feature is the alternating unstressed and stressed syllables with a clear triad: pro-BA-bil-I-ties. The 3rd syllable carries primary stress, and the sequence /ˌprɒb.əˈbɪl.ɪ.tiz/ requires maintaining a crisp /b/ onset and separating the syllables just enough to hear each part, especially when spoken quickly.

- US: rhotic /ɹ/ and clearer /ɒ/ in first syllable; reduce second syllable to /ə/, maintain /ˈbɪl/ as the core; final /tiz/ stays crisp. - UK: more frequent schwa in initial syllable, slight non-rhoticity; keep /ˈprəˈbɪl.ɪ.tiz/ with a slightly lighter second syllable. - AU: vowel reductions are common; keep ending /tiz/ while letting preceding vowels shorten; aim for a relaxed but precise articulation.

probability comes from the Late Latin probabilitas, from probare ‘to prove’ or ‘to test’ with probus ‘good, proved.’ The term entered English in the 15th century within philosophical and mathematical discourse, originally tied to the notion of things being worthy of proof. By the 16th–17th centuries, probabilities began to denote the measure of likelihood rather than moral worth. The modern mathematical sense emerged with the development of probability theory in the 17th century (notably Pascal, Fermat) and the rigorization of statistical methods in the 18th–19th centuries. The plural form probabilities, used since at least the 18th century, refers to multiple possible likelihoods or a distribution rather than a single fixed value. It now appears across statistics, finance, risk assessment, and everyday decision-making. First known use in English literature is attested in the 15th–16th century, with rapid expansion as gambling, astronomy, and later data science popularized the concept of quantifying uncertainty.
