1. We draw a card from a standard deck. What is the probability that it is a Jack, Queen, King, or it is red?
2. I have two standard, six-sided dice, one is brown, and the other is black. I roll them both. What is the probabilty that the sum of the number that I roll is less than 4?
1. There are 52 cards in a standard deck. There are 4 jacks, 4 Queens, and 4 Kings. In addition to this, there are 26 red cards
(4+4+4)/2= 6 (because 2 out of the 4 jacks, queens and kings are red)
32/52 is the probability.
You can solve it from here
2.Total possible number of combinations
The number has to be less than 4,
So the probability is 1/9
