4(25-1)
4(24)=96
Do parentheses first before other operations.
There is a 99.3 chance that neither occur cause you would add 0.3 and 0.4 together and get 0.7 then you would subtract 100 and 0.7 and get 99.3. So your answer is 99.3. Hope this helped :D
If you are rounding it to the nearest tenth then it would be 60% because the unit is above 5.
