[Maria Williany]

A card is drawn and replaced in na ordinary deck of 52 cards. How many times must a card be drawn so that (i) the probaility of drawing one heart be greater than ½?

[skaa]

It is the same problem if you want to solve:
How many times must a card be drawn so that the probability of never drawing a heart be lesser or equal than ½?

\(\left ( \frac{3}{4} \right )^n\leq \frac{1}{2}\)

n=3
