Question 389684
The probability of picking a red card from an ordinary deck of 52 cards is 0.50.  ===> The probability of NOT picking a red card is 0.50
===> The odds in favor of obtaining a red card  = prob'y of picking a red card/prob'y of not picking a red card  = 0.50/0.50 = 1:1, i.e., 1 is to 1.
