Step-by-step explanation:
The formula to find the hypotenuse of a right triangle is as follows,
The line is supposed to be longer on the rooting but it won't go any longer so we just have to make do.
Anyways, a is 1 side length and b is the other. Doesn't matter which one you make b or a.
Now you just plug in and solve
(that's after you square it)
add them
simplify
5.83095189485
you can just stop at the hundredths place
5.83
You can estimate that it's about 6
and 6 is your answer

Answer:

Step-by-step explanation:
First ball:
Probability of drawing a white ball is 5/8
Probability of drawing a black ball is 3/8
Second ball:
This depends on the first ball drawn, lets say you drew a white ball initially, 4 white balls are left out of 7 balls in total. The probability of a white ball in the second pick is 4/7.
Total probability of drawing two white balls is 5/8*4/7 (since they are independent events).
If you picked a black ball initially, picking another black ball would have a probability of 2/7, on similar grounds , total prob for 2 blacks would be 3/8*2/7.
The probability that you pick 2 balls of same color is (5/14 + 3/28) = 13/28. (Since they are mutually exclusive events)
