A. 2/3

B. 1/2

C. 1/3

D. 1/4

QUICK ANSWER…

C

DETAILS…

If two numbers are removed at random from the numbers 1, 2, 3, and 4, the probability that the sum of the numbers removed is even will be = 1/3

Removing two numbers gives:

(1, 2), (1, 3), (1, 4), (2, 3), (2, 4), (3, 4) = 6 combinations.

RELATED!  The table above shows the number of pupils in each age group in...

The number combinations that will add up to an even number will be

= (1, 3) and (2, 4) = 2 combinations.

So, the probability that the sum of the numbers removed is even will be = 2/6 = 1/3

Now for the right answer to the above question:

  1. Option A is incorrect.
  2. Option B is not correct.
  3. C is correct.
  4. D is not the correct answer.
