Probability
Probability puzzles require you to weigh all the possibilities and pick the most likely outcome.

If I have:

a normal coin with a heads and tails;

a 6-sided die;

and a bag containing 4 blue and 2 red marbles,

what is the probability of me flipping a heads, rolling a 4, and picking out a red marble?

a normal coin with a heads and tails;

a 6-sided die;

and a bag containing 4 blue and 2 red marbles,

what is the probability of me flipping a heads, rolling a 4, and picking out a red marble?

### Answer

Probability of flipping a heads: 1/2Probability of rolling a 4: 1/6

Probability of selecting a red marble: 2/6

Then multiply the results, so:

1/2 x 1/6 x 2/6= 1/36 or 0.027 to 3 decimal places
