Question 631382: Please help me solve this Problems.
1. Numbered disks are placed in a box and one disk is selected at random.If there are 4 red disks numbered 1 trough 4, and 2 yellow disks numbered 5 thought 6, find the probability of selecting a disk numbered 3, given that a red disk is selected.

2. a card is dealt from a 52 card desk. What is the probability of not being dealt a queen of hearts?
3. find the measure of complement of the angle.

Hi,

 6 disks, 4 red(numbered 1-4) and 2 yellow(nubered 5-6)

P(3, given red) = %281%2F6%29%2F%284%2F6%29+=+1%2F4

a card is dealt from a 52 card desk: P(not H Queen) = 1+-+1%2F52+=+51%2F52

22 1/2 degrees angle:  Complement is (90- 22 1/2) = 67 1/2
