There are 11 small jars on a table.
3 are Honey.
8 are Jam.
Rosie take 2 at random.
Work out the probability that she takes at least on jar of honey.

There are 11 small jars on a table and 3 of 11 are jars of honey.

=> Probability that Rosie takes at least 2 jars honey:

P = P(Rosie picks 1 jar of honey) + P(Rosie picks 2 jars of honey)

  = (3/11) x (8/10) + (8/11) x (3/10) + (3/11) x (2/11) =  0.486 = ~0.49

Hope this helps!

Let x be the third side. The two cases that allow us to determine the length of the third side are: (1) let x be the hypotenuse and (2) let 8 be the hypotenuse and solve for x. Through the Pythagorean theorem,
 
Case 1.           x² = 8² + 5²       ; x = 9.4
Case 2.           8² = x² + 5²       ; x = 6.2

Thus, the difference is approximately 3.2.
