Question

Imagine each letter of the word “mathematical” is writte on individual pieces of paper and placed in a bag. Should you pick a random letter from that bag, what is the probability that you pick a vowel?

Answer 1

Respuesta:

If we decide to allow letters to be repeated in the bag, then the probability will be P(A) = $\frac{4}{12}$ with Ω={m1, a1, t1, h, e, m2, a2, t2, i, c, a3, l} and A={a1, e, a2, i}. In this case P(A)≅0.33 aprox. 33%

If on the contrary, the repeated letters appear only once on the bag, the probability will be P(B) = $\frac{3}{8}$ Ω={m, a, t, h, e, i, c, l} and B={a, e, i} In this case  P(B)≅0,375 aprox. 37,5%

Básicamente, la probabilidad cambia si permitimos en la bolsa letras repetidas o no. Una vez que decidimos en torno a esto, la probabilidad se calcula como $P=\frac{numero~de~vocales~en~la~bolsa}{numero~de~letras~en~la~bolsa}$
