4/7

Step-by-step explanation:

even: 2, 4, 6

less than 2: 1

total number of cards of interest: 3 + 1 = 4

total number of cards: 7

P(even or less than 2) = 4/7

4/7

Step-by-step explanation:

Let's find how many numbers are even: 2, 4, and 6. That's 3 even numbers.

How many numbers are less than 2? 1. There's only 1 number less than 2.

There is a total of 7 cards. 3 out of 7 of them are even, so our probability of choosing an even number is 3/7. 1 out of 7 of them is less than 2, so our probability of choosing a number less than 2 is 1/7.

Now, because the operation is "or", we add these two fractions:

3/7 + 1/7 = 4/7

The answer is thus 4/7.

something that characterises a right triangle is the fact that we may use pythagoras' theorem to find any one of its sides given that we have the length of the other two sides. here, we have the length of the hypotenuse, √(87) yd, and one other side, √(23) yd, thus we can easily find the length of the remaining side using pythagoras' theorem as defined below:

c^2 = a^2 + b^2, where c is the length of the hypotenuse, and a and b are the lengths of the other two sides.

thus, given that c = √(87) and a = √(23), we may substitute these into the formula we defined above to get:

c^2 = a^2 + b^2

(√87)^2 = (√23)^2 + b^2 (substitute c = √87 and a = √23 into the equation)

87 = 23 + b^2 (evaluate (√87)^2 = 87 and (√23)^2 = 23 - remember that the square root of a number, squared will equal that very same number)

64 = b^2 (subtract 23 from both sides)

√64 = b (take the square root of both sides)

8 = b (evaluate √64 = 8)

therefor, the length of the unknown leg in the right triangle is 8 yd (first answer).
