ANSWER :
27/50
EXPLANATION :
From the problem, we have the following results of throwing a cube with 1, 2, 3, 4, 5 and 6. % and 6 are neglected in the result.
We have 50 results.
1, 2 and 3 represent a success shot.
4 represents a miss.
We need to count how many have 5 numbers and 6 numbers of 1, 2, 3 in the result.
These highlighted results have 5 numbers or 6 numbers of 1, 2, 3
or just simply look for the results with one 4, or nothing.
There are 27 out of 50 results.
The probability will be 27/50
