I have 2 questions.

1) Of the 100 students enrolled at the dance studio, 50 take ballet and 24 take

tap dancing. Eight of the students who take ballet also take tap dancing. If

a student at the studio is chosen at random, find the probability that they take ballet, if it is known that they do not take tap dancing.

2) A shape is randomly selected from the following quadrilaterals: parallelogram,

rhombus, rectangle, square, and trapezoid. What is the probability that it has four right angles, given that it has four congruent sides? (Is this dependent?)
