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!

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2

step-by-step explanation:

the final amount you will pay is $68.04.

the tip is determined by the pre-tax amount, so we calculate the tip based on the original bill, not after we've added sales tax.

to find the tip:

we can divide 54.00 by 100 to get 1% of 54. then we multiply that by 18.

54 / 100 = .54

.54 x 18 = 9.72

tip = 9.72$

to find the tax:

we can divide 54.00 by 100 to get 1% of 54. then we can multiply that by 8 to get 8%.

54 / 100 = .54

.54 x 8 = 4.32

tax= 4.32

now we can add the tip and tax to the bill to get our total.

54 + 9.72 + 4.32 = 68.04

total: $68.04
