Answer: D) 1/14
Work Shown:
There is 1 orange marble out of 7 total. The probability of picking an orange marble is 1/7. Let A = 1/7 which we'll use later.
The probability of flipping tails is 1/2 because 1 side is tails out of 2 sides total. Let B = 1/2
Multiply A and B
A*B = (1/7)*(1/2) = (1*1)/(7*2) = 1/14
This represents the probability of getting an orange marble and flipping tails.
We are able to multiply the probabilities because the two events (picking a marble and flipping a coin) are independent.
