Question 277222
Question 1: Two cards are drawn at random from a standard deck of 52 cards. What is the Priobability that You get at least one Jack?
----
P(at least one Jack) = 1 - P(no Jack)
= 1 - 48C2/52C2
= 1 - 0.8507
= 0.1493
=====================================

 
Question 2: You have a bag of ping pong balls. 
8 of them are red, 3 are white, and 6 are green. 

You take 1 ball out and place it on the table, and then you take another ball out and place it on the table also 
-----

A) What is the Probability(at least one ball is green)
= 1 - P(none green)
= 1 - (11/17)(10/16)
= 1 - 0.4044
= 0.5956
