A box contains 24 light bulbs, of which two are defective. If a person selects 10 bulbs at random, without replacement, what is the probability that both defective bulbs will be selected?
The probability that both defective bulbs will be selected is 0.16

Suppose that 10 cards, of which five are red and five are green, are placed at random in 10 envelopes, of which five are red and five are green. Determine the probability that exactly x envelopes will contain a card with a matching colour (x = 0, 1, ... , 10).
A box contains 24 light bulbs of which four are defective. If one person selects 10 bulbs from the box ina random manner, and a second person then takes theremaining 14 bulbs, what is the probability that all fourdefective bulbs will be obtained by the same person?
Suppose that one card is to be selected from a deck of 20 cards that contains 10 red cards numbered from 1 to 10 and 10 blue cards numbered from 1 to 10. Let A be the event that a card with an even number is selected, let B be the event that a blue card is selected, and let C be the event that a card with a number less than 5 is selected. Describe the sample space S and describe each of the following events both in words and as subsets of S:
a. \({\bf{A}} \cap {\bf{B}} \cap {\bf{C}}\)
b. \({\bf{B}} \cap {{\bf{C}}^{\bf{C}}}\)
c. \({\bf{A}} \cup {\bf{B}} \cup {\bf{C}}\)
d. \({\bf{A}} \cap {\bf{(B}} \cup {\bf{C)}}\)
e. \({{\bf{A}}^{\bf{c}}} \cap {{\bf{B}}^{\bf{c}}} \cap {{\bf{C}}^{\bf{c}}}\)
A deck of 52 cards contains four aces. If the cards are shuffled and distributed in a random manner to four players so that each player receives 13 cards, what is the probability that all four aces will be received by the same
player?
Question:Suppose that a point (X, Y ) is chosen at random from the circle S defined as follows:\({\rm{S}} = \left\{ {\left( {x,y} \right):{x^2} + {y^2} \le 1} \right\}\)
a. Determine the joint p.d.f. of X and Y , the marginal p.d.f. of X, and the marginal p.d.f. of Y .
b. Are X and Y independent
