What is the number of possible outcomes when tossing 4 coins at once?
Sergio [31]
When you are doing an equation like this, multiply every variable by the next. For example, if you had how many ways could 5 colors be arranged, you would do 5 times 4 times 3 times 2 times 1, because there are 5 options for space 1, 4 for space 2 and so on. For this equation, the first coin you toss has 2 possible options, and so do the other 3 coins. So 2 times 2 times 2 times 2 = 16. The answer is A. I hope this helped! Please give brainliest!

Nutka1998 [239]
To compare units either of them have to change to be the same unit

either change inches to yards, or yards to inches.

1 yard is 36 inches, so
3 yards = 3 × 36 = 108 in

100 in < 108 in

3 yards is greater.

nadezda [96]

Yes, I would play the game, because the probability of winning is 13/18.

Probability:

Probability refer the possible occurrence of any particular event.

Given,

A game where two players each throw two dice each. if any one die matches the other, you win a dollar. if there is no match, you lose a dollar.

Here we need to find whether we able to play this one or not.

To find that one, first, we have to identify the winning scenarios,

Let us consider five winning scenarios. Lets represent the dice outcomes as A, B, C, and D, where your dice are A and B and the other player's are C and D. The five scenarios are:

1) A = B

2) A = C

3) A = D

4) B = C

5) B = D

We know that the total possible outcomes is 6^4. We can go through each scenario and count the possible outcomes. We must be careful to avoid overcounting.

Based on this,

The probability that none match is

=> 6*5*4*3/6^4

=> 360 / 1296

=> 5 / 18

So, probability of winning is,

=> 1 - 5/18

=> 13/18.

So, based on the probability the chance of winning is high. So, we can play it.
