Probability( Pulling a diamond) = 1/4
Propability(Rolling a 1)  = 1/6 

The 2 events are independent so the probabilities are mulitplied:-

Required probability  = 1/4 * 1/6 = 1/24 Answer

Answer: 4.2%

Step-by-step explanation:

The deck has 52 cards, and a standard deck has 13 cards of each type, so there are 13 diamond cards.

Then the probability of drawing a random card that is a diamond card is equal to the number of diamonds card divided by the total number of cards:

p1 = 13/52 = 0.25

now, for the dice we have that the dice has 6 sides, but only one side has a 1, so the probability is;

p2 = 1/6 = 0.167

Now, the probability of both events happening at the same time, is equal to the product of both probabilities is:

P = p1*p2 = 0.25*0.167 = 0.042

So the probability is 0.042*100% = 4.2%

Adding negative numbers<br> 5+ (-4) =
anygoal [31]

Answer:

1

Step-by-step explanation:

Follow the signs rule:

IF:

There is a + sign, and the number directly next is +, add

There is a + sign, and the number directly next is -, subtract

There is a - sign, and the number directly next is +, subtract

There is a - sign, and the number directly next is -, add

In this case, there is a plus sign, and a negative sign, therefore, subtract:

5 + (-4) = 5 - 4 = 1

1 is your answer.

A triangle has an area of 35 square inches. the length of one of the sides it 10 inches. what is the length of the perimeter? in
Serggg [28]
The perimeter would be about 34.4 because if you choose the bottom side to be ten, by multiplying 35 by 2 to get 70 you can divide by 10 to get 7. Since you know the height and width, you can use pythagorean theorem, a^2 + b^2 = c^2. Plug in the numbers you have 10^2+7^2=c^2. c^2=149, so if you square root 149 you will get a irrational number but when rounded you get 12.2- so that is one side multiply by 2 and get 24.4- and add 10 to get 34.4
