Question

A school newspaper reporter decides to randomly survey 10 students to see if they will attend Tet festivities this year. Based on past years, she knows that 35% of students attend Tet festivities. We are interested in the number of students who will attend the festivities. Where applicable, your entries must be either fractions in "p/q" format, or decimal values accurate to nearest 0.01 .

If X denotes the random variable we wish to measure, then X is the number of students .

X takes on integer values from to .

X is a random variable that follows a distribution.

How many of the N students do we expect to attend the festivities? E[X]=

Find the probability that at most 4 students will attend. P(X≤4)=

Find the probability that more than 3 students will attend. P(X>3)=
