I am not sure but I think the probability of a circle being chosen first is 4/13
because 13 is the amount of shapes in total, and 4 is the amount of circles. I hope you found this helpful.
The answer is .
There are five squares, two triangles, two ovals, and four circles.
So, total shapes are =
The probability that the first chosen shape will be a circle is given by :
Note: 4 because any 1 out of 4 can be selected.
because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
