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)

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**

26 red cards + 6 black ( J - Q -K)

32 out of 52 = 8/13

36 possible rolls

the rolls that are less than 4

11

12

21 3 out of 36 1/12
