Answer:
The correct answer option is 1/2.
Step-by-step explanation:
We are given a tree diagram showing all the possible outcomes of flipping three coins.
We are to find the probability of getting at least two 'tails' on the coins.
To find this, we will count the number of outcomes with two or more tails and find its ratio to the total number of outcomes.
P (two tails) = [tex] \frac { 4 } { 8 } [/tex]= 1/2
