Determine which of the given procedures meets the criteria of a binomial experiment. Answer O counting the number of words in an essay from each student in the class. Asking people to choose which of the 3 cosmetics brands they like the most. Selecting 4 out of 11 toys from the box and counting the number of toy cars selected.

A student takes an exam containing 16 true or false questions. At least 11 correct answers are required to pass. If the student guesses, what is the probability that he will pass? Round your answer to the nearest ten-thousandth, if necessary. Answer

\begin{tabular}{|l|l|}\hline 3. Combien de chances a-t-on d'obtenir un \\ nombre pair en lançant : \\ - un dé (6 faces)? \\ - deux dés (somme des 2 dés)? \\ \hline\end{tabular}

Two dice of the colours red and blue are thrown. (a) Write the sample space in ordered pair form. (b) Find the probability of getting; (i) 1 on blue die or 6 on red die (ii) 3 on blue die or 5 on red die (c) Show the sum of the elements of each ordered pair (d) Calculate the probability of getting;

The probability density function of random variable \( X \) is given by: \[ f(x)=\left\{\begin{array}{cc}k e^{x+1}, & -2 \leq x \leq 2 ; \\ 0, & \text { otherwise. }\end{array}\right. \] Then \( k \) is equal to:
