For every 8 tokens you have your friend has 3.
after you give half of your tokens to your friend your friend now has 18 more tokens than you.
how many tokens did you start with.
probability that both cans were regular soda =
we are given 12 total number of cans; 4 cans have been accidentally filled with diet soda.
probability that first can is a regular soda:
outcome that first can is a regular soda will give us the number of regular soda available which are 4
using formula of probability
total possible outcomes are, n(total) = 12
desired outcome: 4 (cans of regular soda)
p(1st can) = =
probability that 2nd can is a regular soda:
as we have already taken a can of regular soda from the pack, the total soda in the pack now 11 and the regular soda left are 3.
total possible outcomes are, n(total) = 11
desired outcome: 3 (cans of regular soda as one has already been taken)
p(2nd can) =
probability that both cans are regular soda:
p(both) = p(1st can) × p(2nd can)
call segment cd's length x. because dc and ab are parallel, angle acd and cab, so triangles adc and abc are similar and we can set up the equation x / ac = ac / ab, or x / 5 = 5 / 4 and x = 25/4.
c = 27
given = ( cross- multiply )
4c = 3 × 36 = 108 ( divide both sides by 4 )
c = 27
note that = in simplest form
after you give half of your tokens to you...
