Answer:
a) 1/2
Step-by-step explanation:
All we have to do is simply find the probability of selecting a triangle, find the probability of selecting a circle and then add them together.
There are a total of 10 shapes in the box.
There are 3 triangles, so, the probability of picking a triangle is:
3/10
There are 2 circles, so, the probability of selecting a circle is:
2/10
Adding them together yields:
3/10 + 2/10 = 5/10 = 1/2
The probability of selecting a triangle or circle is 1/2.
