Suppose that two balanced dice are rolled. Let X denote the sum of the two numbers. Userandom-variable notation to represent the event that the sum of the two numbers is less than 4.28)A){X Y < 4}B){X K 4}

Title:

Step-by-step explanation:

Two balanced dice are to be rolled here.

On each dice the outcome varies from 1 to 6.

If we denote, one of the die's outcome by X and for the other one we use Y, then the situation of getting the sum less than 4 can be represented by X + Y <4.

Hence, the sum will be either 2 or 3.

The total of 36 combinations can be found.

The probability of the sum of the outcomes less than 4 is .

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%

no one knows lol
