To find the probability, we just need to divide the amount of possibilities that represent sucess, by the total amount of possibilities.
We have four possibilities representing sucess(0, 1, 2 and 3), and a total amount of eight(0, 1, 2, 3, 4, 5, 6, 7).
Our probability is:
![(4)/(8)](https://img.qammunity.org/2023/formulas/mathematics/high-school/rpyzx290k6nz1mzc52ev9fo170rnmglnxz.png)
Writing this as a percentage:
![(4)/(8)=(4)/(8)*(12.5)/(12.5)=(50)/(100)](https://img.qammunity.org/2023/formulas/mathematics/college/qmhb077cb62sio5r13ar09ns5wq0xftqru.png)
We have a probability of 50%.
