+47 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?
+201 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)
6+26=32
32/52 is the probability.
You can solve it from here
2.Total possible number of combinations
6*6=36
The number has to be less than 4,
so
1+1
1+2
2+1
1+1
4 combinations
4/36=1/9
So the probability is 1/9
+36916 26 red cards + 6 black ( J - Q -K)
32 out of 52 = 8/13
36 possible rolls
the rolls that are less than 4
